Abstract

In severe vibration environment, whole-spacecraft isolation is applied to increase the success probability of launch. For keeping the spacecraft safe, a new structure of whole-spacecraft isolation using viscoelastic damping material (VEM) is presented. First, the models of the VEM are described, and the influencing factors of the damping are analyzed. Then the significant of stiffness, area and geometry for VEM in practical use processing is proved through the simulation experimentation of the VEM we designed. Finally, the performance of new whole-spacecraft isolation structure is evaluated in varying operational modes by simulation experiments. Results show that VEM applied in the new whole-spacecraft isolation is reasonable, and the vibration environment of satellite is improved.
