| Abstract: |
| In this paper, the impact of low impact pyrotechnic separation device during the separation process is studied, and the mechanism of its separation impact is analyzed. Taking a low impact pyrotechnic separation device as a typical example, the impact reduction optimization design research and experimental verification are carried out from three aspects: impact generation source, structural design, impact blocking and absorption. The results show that the impact reduction optimization design methods can effectively reduce the separation impact of the pyrotechnic separation device, which can provide a reference for the subsequent design of similar devices. |
