On the stage of the speech of the program "Open Talk", a man stood up to thank Liang Jianying, a high-speed rail design engineer, and made the audience look confused.
"Designer Liang, thank you for leading the team to design the high-speed rail, which promoted my marriage with my wife."
Liang Jianying
The man's gratitude made Liang Jianying even more confused, how did the high-speed rail he designed become a condition for promoting the marriage of others?
It turned out that this man from Chengdu had fallen in love with a Shaanxi girl, and when the two were about to talk about marriage, the girl's parents did not agree to the marriage of the two because they felt that the boy's family was in other places, and just when the two were about to break up, the operation of the high-speed rail brought a glimmer of life to this "long-distance love".
The high-speed train from Chengdu to Xi'an takes only four hours to reach, and compared with the previous dozens of hours of green-skinned trains, the speed of high-speed rail provides great convenience.

What did Liang Jianying do to accelerate the development process of China's high-speed rail? How did she become the only female engineer in China's high-speed rail?
Don't let the eyebrows be shaved, go deep into the danger to do research
In 1995, Liang Jianying, a graduate of Shanghai Railway University, was assigned to The Sifang Locomotive and Rolling Stock Factory in Qingdao, Shandong Province, on demand.
Liang Jianying, a major in power transmission and control at the university, came to the motor vehicle room to study and research as desired.
Liang Jianying, who came to the workshop as a designer, worked diligently, studied seriously, and worked hard to exert his expertise, so that the leaders were also surprised.
In 2006, the leader personally appointed Liang Jianying as the designer of a new generation of high-speed EMUs, leading more than a dozen people to carry out project research and development, Liang Jianying who received the project was nervous, this was the first time he personally designed a high-speed train, the long-dreamed Liang Jianying could not hide the joy in his heart, and at the same time had concerns about design.
But Liang Jianying did not disappoint, and her research and development results shocked China and abroad.
Liang Jianying led the team to complete the leap from 200 km /h to 300 km/h. Whether it is from key technology research to program design, from simulation analysis to experimental verification, Liang Jianying has been successful step by step.
In December 2007, Liang Jianying led the team to successfully break through key technologies such as aerodynamics and body steering, and successfully developed the first EMU with a speed of 300-350 kilometers per hour in mainland China. Chief designer Leung Kin-ying became famous.
Everyone looked at this high-speed rail "towel lady" with awe and admiration. Liang Jianying, who lived up to expectations, shocked the world again in 2010.
In 2010, CRRC Sifang developed the CRH380A high-speed EMU, and Liang Jianying once again picked the girder and served as the chief designer of the EMU.
The new generation of high-speed trains reached a speed of 380 km / h! The speed of the previous green-skinned train was only floating up and down at a speed of 140 km/h. The speed of the new generation of high-speed trains is more than 2.7 times faster than the previous speed.
With this, China's high-speed EMUs also became the fastest EMUs in the world at that time, and it was also the world's highest-tech EMU at that time.
The international community believes that this should be the highest speed in China at the tail of the crane in the field of high-speed rail, but Liang Jianying's next "innovation" has left the Western media dumbfounded.
Liang Jianying, who created a high-speed train with a speed of 380 km / h, did not stop the pace of exploration due to a momentary success, but made Liang Jianying feel that no matter how hard he worked, we should be able to reach a higher height.
Seven to nine in the morning has become the norm for Liang Jianying, and even squeezed the time to eat and sleep to supervise the latest progress of the experiment.
Liang Jianying's efforts have yielded great gains.
In the course of the experiment, Liang Jianying created the maximum test speed of more than 600 kilometers per hour, once again becoming the highest in the world.
At that time, the maximum test speed in France only reached 574 km / h, and Liang Jianying and his team's "dark horse was born" caught the West off guard.
The EMU that came up to the test speed surprised Liang Zhenying and decided to conduct a trial operation test. After several years of energy investment, really came to the field test, Liang Zhenying was worried.
Field tests are not as good as simulation tests in the laboratory, and need to consider factors such as wind speed resistance, climate, etc., and everyone dares not slack off, staring at the screen to pay attention to the latest speed operation.
The speed of the train was like a hurricane, speeding by, 482 km / h. The number 482 made the researchers in the control room can no longer suppress their inner excitement, shouting loudly and applauding.
Although China's technology has made new progress in "fast", "stability" is also a necessary condition. At that time, Liang Jianying and his team did not consider this problem, and a field trip to Switzerland inspired Liang Jianying.
Because of professional habits, Liang Jianying habitually buys a ticket wherever he goes to feel the "performance" of the train. The head coach of the high-speed rail who had never been motion sickness was actually motion sick.
"I can't breathe, I can't stand still, and I'm not in the mood to enjoy the view." It was not until the train arrived at its destination that Liang Jianying slowed down for a long time before reacting from the dizziness.
This "dizzy" journey made Liang Jianying determined: for China's trains to be "stable", to make Chinese passengers feel comfortable and relaxed.
This led to the later legend that "a signature pen stood firm on a Chinese train".
Although the speed and stability have improved, Liang Jianying feels that technical excellence is necessary for the passenger experience to be better.
In order to test the performance of motor vehicles in many ways, Liang Jianying led the team to travel all over the motherland. In order to test the performance and system assembly of the new train, Liang Jianying came to Hunan with a team. The rainy weather in Hunan has put a lot of people in a "dilemma".
The laboratory is closed to the wet tide, coupled with the fact that it is summer, the sweltering and humid weather in Hunan makes researchers from the north "cry bitterly." "I wasn't used to eating and living, and I was covered with eczema.
If it weren't for his love for the research of the mobile group, he would probably have left Hunan a long time ago.
A crowd even teased each other: this is more effective than diet pills.
But the weather in Hunan did not crush this unaccustomed group of northerners. A dozen hours in the lab is the norm.
In order to detect the test of the motor vehicle on the running track in real time, Liang Jianying personally lay on the bottom of the car for testing. No one will listen to anyone. After staying for several hours, I finally called my colleagues for help because of my stiff waist.
Everyone else advised Liang Jianying to hurry up and rest, but Liang Jianying himself was "stubborn". Even if he was lying on his stomach frozen, his mobile phone did not leave his hand, asking to see the results of the first-hand motor vehicle track test.
Liang Jianying's seriousness is in everyone's eyes, and he will sincerely show his respect for this woman. The test of the Lanzhou line made everyone more impressed with Liang Jianying.
In 2014, the high-speed rail line from Lanzhou to Urumqi was opened for operation. The trial operation of motor vehicles in two areas with perennial weather and winding terrain has not only attracted the attention of domestic people but also attracted the attention of foreign media, who are curious about how China can make two cities with rugged terrain complete "connectivity and interconnection." ”
These two areas are known by world geographers as windy areas that stretch for hundreds of miles. Large temperature difference, high altitude, strong ultraviolet rays, strong wind and sand, two-thirds of the year are windy, the wind level is above the eight levels, the strongest can reach 12 levels.
In order to better test the impact of wind speed on the tilt of the train, Liang Jianying led the team to select the most severe weather, go deep into the most dangerous areas, and test the train against the strong winds of twelve levels.
Liang Jianying paced back and forth in the train, while recording the latest experimental data, while studying at what time to slow down or stop the train, while feeling the tilt angle of the body and the vibration of the body, Liang Jianying walked in the workshop for several hours, never stopped.
Urumqi terrain is rugged, the train in the trial operation test, there is a section of the test road is loess road, the road surface is rugged with sand and gravel, each test ends, the seat chassis will be covered with dust, in order to ensure the accuracy of daily data, Liang Jianying will stay behind to personally explore the bottom of the car to wipe, to protect the normal operation of the machine, Liang Jianying, who started work at seven o'clock in the morning, always returned to the residence late at night, as always, never absent.
With the joint efforts of Liang Jianying and the team, the high-speed rail train in Lanzhou --- Urumqi was successfully put into trial operation, and the high-speed rail was completed in a severe area, and Liang Jianying was the first person in China.
In 2015, the mainland proudly claimed to the world that high-speed rail is a golden signboard in China.
In particular, fuxing was invested in research and development.
As early as 2013, fuxing has been put into operation and research and development, but in order to present the best performance of the motor vehicle.
Leung Kin-ying and his team have been "painstakingly working hard" for more than a few years.
The front design of the Fuxing put forward forty-six concepts, from which repeated screening, repeated comparison, the implementation of twenty-three industrial design schemes for simulation, and a large number of simulation calculations and simulation tests, costing a lot of manpower and material resources, the final front data printed A4 paper model is stacked more than a meter high.
Although the noise index of the CRH380A EMU developed by the team at that time has been perfected, the team's team decided to continue the challenge: "We want to reduce the noise of more than three decibels on the basis of crH380A." ”
Under the technical conditions of the world at that time, even reducing one decibel was a great problem, let alone three decibels. Liang Jianying's "bold words" are not favored by Western countries, and they feel that Liang Jianying's mouth is like a hanging river. Liang Jianying and the team did not care what the Western countries thought, but just moved towards their own goals.
More than a year of time, more than 3,000 tests, endless material selection, boring data records. Liang Jianying did it.
In 2017, when the Fuxing was officially unveiled, domestic and foreign media rushed to report on this "legendary" train. The entire section of the Fuxing has reduced drag by 12% and the noise has been reduced by four to six decibels! Far beyond the goals set by the team. The smoothness index of the body has reached the excellent level steadily.
The "perfect" launch of the Fuxing once again refreshed the new height of China's high-speed trains, making the mainland the fastest country in the world in terms of high-speed rail commercial operation. Liang Jianying succeeded.
Since the beginning of 2008, Liang Jianying led the team to create one legend after another, and has won the technical awards promulgated by the state, becoming the only female general of the national motor vehicle engineer.
So, what made Liang Jianying decide to choose a dynamics major with a group of men and become a high-speed rail designer?
Toddler enlightenment The twists and turns of the "way home"
Born in Jilin, Liang Jianying has been curious about the railway station just two hundred meters away from his doorstep since he was a child. Every day after school, Xiao Jianying ran to the track with his friends to watch this "big guy" with smoke on his head.
Every day, Xiao Jianying wonders when he can get on this train and see what's inside. One of his parents' outings made Xiao Jianying fulfill his wishes.
Liang Jianying, who entered the train, was excited, curious about the structure of the train, and had a strong interest in how the train traveled on the tracks.
It was also this outing that gave Liang Jianying the idea of learning the structure of the train.
To this end, when choosing a major in college, Liang Jianying did not hesitate to choose a power control major with one of the few women. After that, an experience of returning home made Liang Jianying vow that he would become an engineer in the EMU.
It was the peak time for the return trip home.
In order to grab tickets for more than 30 hours away from home, Liang Jianying and his friends had been lining up at the station for a day and a night. When it was finally time to queue up for Liang Jianying, the conductor told Liang Jianying that there were no tickets.
Liang Jianying, who had no choice but to buy a station ticket to Shenyang first and then transfer to Jilin. A girl's family stood on the bus with a large bag of luggage for more than twenty hours, and only Liang Jianying understood the heartache.
Thinking that Liang Jianying's way home was already very bumpy, the friend's story made Liang Jianying feel more helpless.
"I was squeezed to stand on one leg for more than a dozen hours."
"I had a seat ticket, but because there were so many people, I couldn't get through at all, so I was squeezed into the middle and stood for more than twenty hours."
Under the wave of "Spring Festival Fever" in the 20th century, the wanderers without a little skill could not sit on the car at all, leaving only the endless bitterness of the wanderers and countless heartaches.
At that time, Liang Jianying was wondering when it would become easier to go home. Back at school, Liang Jianying vowed that he would have to become an EMU design engineer in his lifetime.
Since then, Liang Jianying has worked hard to deepen the field of EMUs, from a technician in a vehicle factory to a high-speed rail EMU design engineer today.
Young enlightenment, made a vow, and fought for more than ten years, liang Jianying is still fighting on the road of EMU design.
Liang Jianying often said that the high-speed train must be in the test, and only through a large number of tests can we know what its performance law is in the state of high-speed driving.
Since 2014, Liang Jianying has led the team to exchange and cooperate with German and Thai EMU designers for many times, and has established joint railway transportation research centers with the United Kingdom, Thailand, Germany and other countries, realizing the cross-ocean of Chinese technology.
Liang Jianying will dedicate most of his life to the Cause of China's EMUs, many times on the day of family reunion, Liang Jianying in order to obtain more accurate data and test out the most optimized program, Liang Jianying has chosen to give up a small family for everyone.
The lack of maternal love of her daughter is the pain that Liang Jianying has been suffering in her heart, as the general manager, she cannot delay the overall progress of the team because of herself.
"I don't regret it!" Dao fulfilled Liang Jianying's determination to dedicate himself to the country.
After more than ten years of hard work in the front line, he led the team to create one after another brilliant that is exclusive to China's speed, and realized the wonderful butterfly change of China's high-speed rail from "following" to "leading".
The name of the hero Liang Jianying deserves to be remembered forever.
