Perturbation Stochastic Finite Element of Mechanical Vibration

Wenhui Mo


Perturbation stochastic finite element of mechanical vibration is introduced. The vibration equation of a system is transformed into a static problem by using the Willson θ method. An improved method of perturbation stochastic finite element is proposed. The formulas of calculating perturbation stochastic finite elements are transformed into linear equations to avoid solving matrix inversion. A numerical example is given in order to demonstrate the proposed.
