| Abstract: |
| Based on LZB multi-impacts model for multibody system, a dynamic model focusing on the guiding process of low-shock separation was established. The effectiveness of the model was verified by experiments using high speed cameras. This study provides theoretical and experimental supports for the future development of the whole process of low-shock separation. |
