摘要
Abstract
In view of the in-orbit multiple locking/unlocking requirements for the solar alpha rotary joints of the Mengtian lab module under docking and transposition conditions,a repetitive automatic locking/unlocking device is designed,where the double four-bar mechanism and the adaptive end effector are applied.In order to validate the function and performance of the locking/unlocking device,the developed product is tested in various states such as vacuum high-temperature,vacuum low-temperature,and atmospheric environment.The results show that the product can realize the repetitive automatic locking/unlocking function in various states.When the rated direct current operating voltage is 28 V,the execution time of the locking action is between 17.09 s and 17.15 s,and the execution time of the unlocking action is between 16.51 s and 16.89 s.The device has the advantages such as high reliability,full angle,and repetitive locking/unlocking in orbit,and has great engineering application potential in the locking/unlocking mechanisms for spacecrafts.关键词
