Other Abstract

In order to solve the problem that the photoelectric instrument may fail when the vibration response of the truss composite structure is too large,the method of applying the viscoelastic constrained damping layer on the truss wall and the box panel is used to reduce the vibration of the whole structure. The finite element analysis software Nastran is used to analyze the vibration characteristics of original structure and truss composite structure with the viscoelastic constrained damping layer under the given working conditions,and the vibration acceleration response curve at the specified location of the truss composite structure is obtained. By using the size of damping factor as the evaluation index of vibration reduction effect,the optimal design parameters of viscoelastic constrained damping layer are obtained through the optimization and comparative analysis of the thickness of viscoelastic constrained damping layer. The experimental results show that the viscoelastic constrained damping layer has a good damping effect on the space truss composite structure. The experimental data and simulation results are consistent,and the damping scheme is feasible.
