| Abstract: | Constrained layer damping treatment is an important dynamic vibration control menthod intensively used in spacecraft structure. This paper introduces the frequency response analysis method for structures with constrainted viscoelastic layers by using commerial finite element software NASTRAN. This method can be used to evaluate the damping effect of constrained layer damping treatment. |
