摘要
In this paper, material properties, geometry parameters and applied loads are assumed to be stochastic, sensitivity computation of structural vibration is presented. The vibration equation of a system is transformed to a static problem by using the Newmark method, and the Taylor expansion stochastic finite element method （TSFEM） is extended for the structural vibration analysis. An example is given, and the calculation results show the validity of the proposed method.
