Finally, it's the turn of the United States to beg us. China has to be out of stock all over the world if it doesn't sell

We know that in recent years, China has made rapid progress in many fields. Some have caught up with and surpassed the same level in the West, but some have reached the forefront of the West and are at the leading level. Take dredger as an example. China has the largest dredger in the world, Tiankun. If you don't believe it, this dredger can dredge 6000 cubic meters per hour.

Of course, this is just the tip of the iceberg in China's successful field. In addition, there is also a proud research in China, that is, in the aerospace field, the shaking table used for rocket launch. In fact, we are only latecomers in this field, because it was the United States that first made research in this field.

But it is obvious that a fast start may not be the first to reach the end. In this field, it is finally our turn to take the lead. And in the words of Russian experts, if China does not sell this thing, the world will have no place to buy it. The American media complained that the United States had never experienced such cowardice.

How important is space shaking table? We know that if mankind wants to further explore space, it must use the power of rockets to launch satellites into space. But rocket launching is not as simple as starting a car, engaging a gear, releasing the clutch and stepping on the accelerator. A wrong step may be just the vehicle stalling, but if the rocket is launched in a wrong step, the consequences may be incalculable.

The rocket is a huge thing. It weighs hundreds of tons. When it is launched, it must be accompanied by a strong shock. If the vibration amplitude is too large, it is very likely to cause equipment failure, thus causing unexpected accidents. In order to solve this problem, experts invented the vibrating table. Its biggest function is to solve the problem of rocket vibration.

However, this technology was only available in the United States before. When China proposed to buy 9 rocket shakers from the United States, the result was as expected and was categorically rejected. China has not given up, and has worked hard to develop 50 ton and 70 ton thrust vibration tables, while the largest vibration table in the United States is only 35 ton.

The United States bought a 50 ton vibrating table from China with $100 million, but China put forward five requirements before selling it. The United States had no choice but to compromise and sign.

First of all, although the equipment was bought by the United States, the Chinese side must send operators to operate it, and the United States has no right to use it directly; Secondly, the United States should not remove or replace parts without authorization, and all parts should be replaced with products made in China; Moreover, it cannot be used for military purposes; Fourth, the parameters obtained from the test must be kept by Chinese personnel; Finally, the United States must not lease the equipment to a third party without China's permission.

American experts said that all along, the United States has made rules and requirements for other countries. It is the first time that the United States has been asked to compromise.
