Research on Vibration Reduction Compatibility for Multiple Transportation Conditions

Abstract

Vibrations in the process of transportation are often neglected in product design. In order to avoid damage to acceleration sensitive equipment or components of spacecraft due to destructive transport load, vibration absorbers are usually installed in the container during spacecraft transportation. How to determine the vibration reduction scheme suitable for different payload weight has become the key point and technical difficulty in the design of vibration reduction in transportation. Aiming at this problem, the size and weight of the target product are analysed, and the vibration features of different sections of the satellite are analysed and tested. On this basis, a general vibration reduction subsystem of the container is designed, which is suitable for three kinds of satellite sections and four types of transportation conditions, and the loading distribution parameters are optimized. Transportation test data show that the vibration reduction effect of the new system for aerospace products meets the design requirements.
