关键词Viscoelastic Damping Aerospace Acceptance Truss Acceleration Applying Constrained Modulus Stiffness
摘要The acceleration response value of space truss and aerospace load structure is exceeded in the acceptance level vibration test.The method of applying the viscoelastic damping layer is used to reduce the vibration of the space truss and the aerospace load structure.The test results show that the damping effect is obvious,and it is needed to determine the structure parameters and material parameters of the viscoelastic damping layer.The structural parameters include the location of the viscoelastic damping layer,the thickness of the damping layer,and the thickness of the constrained layer.The material parameters include the shear modulus of the damping layer,damping factor of the damping layer,and the selection of the constrained layer.With index of damping factor and the resonance frequency of vibration,the influence of structural parameters and material parameters on the damping effect of viscoelastic damping materials is obtained by the optimization and comparison of damping factors.
