Dynamic Optimization Design of Stochastic Finite Element

Abstract

A general model of the optimum design of structural vibration with the random parameters is introduced. Dynamic optimization design of stochastic finite element using the Preconditioned Conjugate Gradient method (PCG) is presented. The vibration equation of a system is transformed to a static problem by using the Willson method and stochastic finite element analysis of structural vibration adopts the PCG.An example is given respectively and the proposed method is robust and efficient.
