| description | The space unlocking device is a key component to realize the connection and separation between spacecraft and its accessories. In order to solve the problem that the non-self-locking thread connection space unlocking device is affected by impact, vibration and other loads during launch and lift-off, which leads to the risk of loosening failure of the main power source（loading nut）, the unlocking mechanism of the non-self-locking thread connection space unlocking device was analyzed. The redundant power source of the redundant drive mechanism was designed by multi-objective optimization algorithm. At the same time, the overrunning clutch was selected as the transmission main body of the redundant driving mechanism, which can ensure the smooth unlocking of the device in the case of failure of the main power source, and effectively avoid the interference between the redundant power source and the main power source in the normal operation of the device. Finally, the dynamic simulation analysis and experimental verification of the space unlocking device driven by the redundant mechanism have been carried out. The results show that the redundant mechanism can complete the unlocking task of the device quickly and reliably. |
