Background
The unlocking release device is used for connecting and separating the fixed structure and the separating structure. Unlocking and releasing devices on the spacecraft are generally used for separating stars and arrows, compressing and releasing a solar sailboard and an antenna and the like. The separation release device is in a locking state before reaching a preset orbit, and is unlocked and released after reaching the orbit to complete the space mission.
The reliability of the separation release and the separation impact play a key role in the completion of the task. With the development of the aerospace technology, the requirements of the aerospace mission on the separation release device are more and more strict, and the trend of improving the reliability and reducing the release impact is the future development of the separation device.
The unlocking and releasing device is divided into an initiating release mode and a non-initiating release mode. The initiating explosive release is to break or shear the connecting pin by using huge energy generated by explosion or combustion of gunpowder, so as to realize unlocking. However, the firer release generally has the disadvantage of large impact force. In order to reduce the separation impact, researchers have designed non-pyrotechnic release devices whose load bearing takes two forms: direct bearers and indirect bearers. The direct bearing mainly refers to thread bearing and comprises a split nut and a non-self-locking thread; the indirect bearing finger force increasing mechanism and the dead point mechanism. The non-explosive release device generally adopts four driving modes of electric driving scroll unlocking, fusing unlocking, paraffin driving unlocking and memory alloy driving unlocking.
