There is depth, there is thought, there is a story
Made in China plays an important role in the rise of China, it can be said that without Made in China, there would be no international status of China today!
On October 31, 2023, the return capsule of the Shenzhou-16 manned spacecraft successfully landed.
Since October 2003, the "Shen V" flight has become China's first successful manned mission.
In the past 20 years, from the Shenzhou series to Chang'e, the mainland rocket industry has flourished. In addition to the outstanding contributions made by astronauts to the manned project, there are also invisible vibration platforms that have also made "great contributions" to the rapid development of the aerospace project.
Made in China can stand in the forest of the world today, and it cannot but be said that the United States has played a certain "role". The United States has taken restrictive measures at different times to curb China's development, on the contrary, it has triggered the spirit of not admitting defeat in the bones of the Chinese, and one by one high-precision technology has broken through, and even reached the world's leading position!
The vibrating table, which is such a "big power heavy weapon", has become a leading global existence after several years of struggle on the mainland, and has been banned from exporting.
In 2020, in the "Catalogue of China's Prohibited and Restricted Export Technologies" issued by the Ministry of Commerce and the Ministry of Science and Technology, a new article 32, "design and construction technology of large-scale vibrating platforms", was added in the ninth category of "professional equipment manufacturing industry", which proves the current strength of large-scale vibrating platforms in the world.
To build a rocket, you can't do without it
For spacecraft, space stations, rockets and other large and heavy components, it is necessary to use a high-thrust electric shaker.
Especially during the launch of a spacecraft, the importance of detecting whether the spacecraft is "good" through a vibrating platform is self-evident. Especially in manned spaceflight, the importance of pre-launch vibration testing is self-evident.
In the past, space launches failed, mostly because the vibration test machine failed!
Therefore, before the launch of the spacecraft, it is necessary to use shaking tables to conduct environmental tests in ground test equipment that simulates these mechanical environments. Continuously test the environmental conditions of the rocket when it vibrates, check whether the components remain intact, and then carry out corresponding rectification and optimization to enhance the success rate of the rocket.
To judge the advanced nature of the shaker, thrust is an important criterion. The thrust of the shaker is uniformly measured in "tons", and 1 ton means that the shaker can produce a thrust of 9,800 Newtons.
U.S. blockades, restrictions
China started late and was subject to a technological blockade from the United States, lacking technical information and experience. Large shakers were originally used in the military field and therefore have a strong military background. With the establishment of diplomatic relations and trade relations between China and the United States, the United States has included large shakers in the embargoed list.
In the 50s of the 20th century, the United States initiated the creation of the Paris Coordinating Committee, which aimed to limit the export of various materials and high-tech products to socialist countries, among which large shakers became the focus.
Initially, the export of shakers to China was completely banned. Even if China is willing to pay a high price, it will be difficult to find someone to ship.
The road to independent research and development
In 1995, "Suzhou Dongling Vibration" was established and began the road of self-development.
In 2002, the first 6-ton air-cooled vibrating table in China was successfully developed.
In 2004, the largest 16-ton water-cooled vibrating table in China was launched, escorting the Shenzhou 6 manned spacecraft, which completely broke the technical blockade and embargo of Europe and the United States on China's large-scale vibration test bench.
In 2006, the world's largest thrust 35-ton electric shaker with independent intellectual property rights was born in Dongling, Suzhou. Participated in the vibration and mechanical dynamic impact tests of all important equipment of manned space engineering in the mainland, from "Shen V" to "Shen IX", from "Tiangong" to "Chang'e".
In addition to Suzhou Dongling, another Suzhou test instrument has also made a major breakthrough.
In 2009, it developed a three-axis co-vibration electrodynamic vibration test system representing the highest level in the field of continental mechanical environmental testing, and the largest 40-ton electrodynamic shaker in China.
Later, it was the appearance of the electric vibrating table with a total thrust of up to 70 tons that shocked the world! Since then, we say that it is far ahead of the world!
70 tons of thrust shaker
For the 70-ton shaker, we have to start with an international exhibition. At that time, representatives of various countries showed their scientific and technological achievements one after another to demonstrate the strength of their countries.
Suddenly, on a huge stand, a giant device of 70 tons attracted everyone's attention. This is not a simple device, it carries the hard work and sweat of Chinese scientific and technological personnel behind it, and it represents a huge breakthrough in China's key technological fields.
This 70-ton electrodynamic shaker is not an ordinary piece of equipment. It is a major feat of the continent in the field of rocket technology, capable of simulating the extreme environment of the rocket when it is launched, ensuring the safety and reliability of the rocket.
Imagine that such a device could be used not only on rockets, but also in a wide range of applications in electronics and automobiles.
The R&D and manufacturing of 70 tons of electric vibrating table is a major feat of China's scientific and technological development, and it also contributes more wisdom and strength to the global scientific and technological progress, of course, the power of the mainland.
The United States will no longer restrict and jam us in this regard, but we will jam the neck of the United States!
