Editor's Note
In order to tell the stories of scientists well and carry forward the spirit of scientists, the Provincial Association for Science and Technology this year continued to launch a series of reports on "Dreamers of Science and Technology" in the new era, selected a group of outstanding scientific and technological workers who have taken root in the frontline for a long time and actively devoted themselves to science, and used the language that the masses like to hear and listen to to, to collect and write their vivid deeds, and to unite with the provincial-level professional media to carry out all-media dissemination through radio, video, the Internet, and other forms, so as to create a good atmosphere in the whole society for vigorously carrying forward the spirit of scientists and reproduce the vast number of scientific and technological workers listening to the party. The vivid practice of following the party.
The publicity activities of "science and technology dreamers" will be normalized and regularized, and the province's science and technology associations at all levels, societies (associations, research associations, promotion associations), colleges and universities science and technology associations, and enterprise science and technology associations will recommend and send outstanding scientific and technological workers to their units, in an eclectic form, which can be news reports, self-reported articles or pictures and videos. This public account will be published on a merit-based basis.
Biography
Zhang Qi, director of the Test Technology Center of the Research Institute of Zhejiang Shuanghuan Transmission Machinery Co., Ltd., has won the honorary titles of "Leading Talent of Scientific and Technological Innovation of the National Ten Thousand Talents Program", "Title of 'Young Pioneer' of Taizhou City", "The First Batch of Outstanding Young Talents of Taizhou City", "Zhejiang Province 'Qianjiang Talent Program'" and other honorary titles.
A few days ago, in the research institute of Zhejiang Shuanghuan Transmission Machinery Co., Ltd., Dr. Zhang Qi fell into contemplation, and what was in front of him was a complex design of the robot dog power transmission system. This was designed not long ago by him and his team members, and it is about to be put into prototype trial production.
2021 is the seventh year that Zhang Qi has entered the double ring transmission, during which he has made outstanding achievements in product research and development, team building, and scientific research services, which has greatly enhanced the core competitiveness and industry influence of the enterprise.
He has won the honorary titles of "National Ten Thousand Talents Program Scientific and Technological Innovation Leading Talent", "Taizhou 'Young Pioneer'", "Taizhou City's First Batch of Outstanding Young Talents", "Zhejiang Province 'Qianjiang Talent Plan'" and other honorary titles, and his team has also been rated as "Zhejiang Province Key Technological Innovation Team" and "Taizhou City Key Technological Innovation Team".
Immerse yourself in research and development
Climb to the heights of technology
Zhang Qi is a native of Xiangshui, Jiangsu Province. In 2013, after returning from studying in South Korea, he gave up the opportunity to work in colleges and universities, and was introduced to Yuhuan as a shortage of talents in Taizhou's "500 Elite Program". The following year, he entered the research institute of Zhejiang Shuanghuan Transmission Machinery Co., Ltd. This is one of the world's largest and strongest professional manufacturers of gear parts. Since then, Zhang Qi has taken root in the grassroots level of Yuhuan Island, in-depth practice, and immersed himself in polishing technology.
In March 2018, after the delivery of a batch of gear samples that he was responsible for research and development, he received feedback from customers that the installation effect was not good and the transmission vibration noise was abnormally obvious. At this time, it is less than 2 months before the time of its products to be launched. Zhang Qi led the team from Yuhuan to Liuzhou, Guangxi for the first time, to conduct field investigation and research, and re-analyze all the relevant data of the transmission.
"During that time, we soaked in the laboratory almost every day, constantly experimenting and revising simulation models, did not sleep for several days and nights, and squinted in the laboratory when we were sleepy." Recalling the situation at that time, Zhang Qi still remembers it vividly.
Kung Fu pays off. Only a week later, Zhang Qi and others came up with a set of solutions, and after being verified by the customer's vehicle test, the overall noise of the transmission was greatly reduced, which greatly shortened the development cycle of the product. At this point, Zhang Qi's hanging heart slowly let go.
With a tenacity that does not give up, in the past seven years, Zhang Qi has overcome technical problems such as gear transmission vibration reduction and noise reduction, high-strength and low-noise gear material development, and high-precision planetary gear transmission.
Outside of work, Zhang Qi likes to read and learn, but the way he reads books is different from ordinary people. He lists the books he wants to read recently, organizes them into a spreadsheet, and sorts them according to information such as authors and content introductions, and selects the books that need to be read the most.
"A person's energy is limited, and it is necessary to absorb knowledge efficiently and do things efficiently. I have a problem in one book, and I hope to find the answer in the next book as soon as possible. He said.
Excellence
Build a great team
One person can go fast, but a group of people can go further. At the beginning of last year, Zhang Qi accepted the company's appointment to organize the establishment of a research and development team. A team of 15 people was quickly formed, and Zhang Qi, as the captain, was strict with everyone and was unambiguous. "Strict enough to be in a report, not a single punctuation can be wrong." He said.
"Once, in order to solve the high noise problem of a gearbox, we did more than 100 sets of experiments in three months, and repeatedly compared and verified. Everyone thought it was no problem, but Teacher Zhang Qi said no. It is precisely because of his strict requirements for excellence that we have accumulated a large amount of valuable engineering experience and test data. Team member Lu Jianhua told reporters.
In the end, the finished transmission was reduced by 5-8 dB on the original noise indicator. The seemingly inconspicuous numbers are a big step forward for the product in the professional world.
Every Saturday afternoon, Zhang Qi also gave up his rest time and led everyone to hold a learning seminar, share cutting-edge technologies and academic journal papers related to mechanical transmission, and master skills in practice.
Up to now, the team has completed the design and development of small differential assemblies, the research of vibration reduction and noise reduction of various automotive transmissions, the design and development of backlash gears for engines, etc., overcome a number of technical problems, and created huge economic benefits for the company.
Talking about the future, Zhang Qi is full of expectations. Next, the team will strive to push the research related to high-precision reducers to the domestic leading and world-class level, and build the research institute into a national technology center and a world-class sub-assembly research institute." There is no end to scientific research, and we are willing to become the 'dream-chaser' who is always on the road. ”
