| Abstract: |
| The work aims to design a kind of general container for satellite product to reduce cost and improve efficiency in view of how to determine and select a damping scheme suitable for different load characteristics has become the key point and technical difficulty in spacecraft transportation vibration damping design. Aiming at this problem, the size interface and weight of the target products were analyzed, and the vibration feature of different transporting conditions of the satellite was investigated and tested. On basis of this, a general shock absorption subsystem for three kinds of satellites and four kinds of transportation conditions was designed, and the loading size parameters were optimized. The first-order vertical fundamental frequency of the system was less than 5.8 Hz. The transportation test data show that the vibration damping effect of the new vibration damping system for aerospace products meets the requirements. |
