On June 25th, China's new generation of carrier rocket Long March seven in Wenchang, Hainan space launch site successfully was launched. At the same time, we received a letter of thanks from the launch command post , thanks to the focus on the first mission to make outstanding contributions.
Henan Yuantai engineer, technology minister Arier Li said that the launch site using the HenanYuantai production of "Our production of the crane and the general crane compared to the biggest characteristics and advantages, is the independent research and development of anti swing technology." Arier Li said, a big difference, the rocket launch any procedure has high requirement for precision, but ordinary crane handling materials will inevitably produce inertia swing phenomenon, to launch trouble.
Our group’s Anti swing technology by the motion simulation, design mathematical model, using computer to control the key components of the operation, the final swing angle decreased to less than 0.2 degree, the swing amplitude is reduced by 95%, the crane can lift a weight, which is as steady as Mount Tai and no longer swing, can precisely realize the operation intention.
It is understood that our group anti swing technology has been awarded the national invention patent, can do the perfect control of the crane, the only one all over the world. Currently, Yuantai crane and the four major satellite launch centers have established a good cooperation relationship. In the future of other major aerospace project, there will be more crane figure from Yuantai crane.
