Abstract

Visco-elastic damping material is applied to a novel type of isolator for the whole-spacecraft passive vibration isolation system, which can be used to improve the dynamic environment during the stage of launch. The results of the simulation and the experiment show that the vibration transmissibility of the mass center decreases more than 40%. The experiments of the isolator with different damping area are performed. The issues of natural frequency drifts and the transmissibility decreases as excitation level rising are discussed. It is demonstrated that the nonlinear of visco-elastic damping material and structure in the vibration experiment is the main influence factors.
