| Abstract: | The connection and separation technology of spacecraft is the key technology in the space transportation system. As the key device in this field, the connection and separation device has been an important research subject for a long time. In view of the requirements of spacecraft connection and separation, this paper proposes a new non-pyrotechnic separation nut device based on vortex coil spring, and completes the structural design. Vortex coil spring is the key part of the device, which directly affects the load-bearing and working characteristics of the device. The tension and torque of the vortex coil spring are analyzed respectively. And through simulation, the characteristics of device in unlocking process are analyzed. |
