RESEARCH OF STOCHASTIC FINITE ELEMENT METHOD BASED ON STRUCTURE DYNAMICAL PROBLEM

Abstract

Abstract: One new three-parameter stochastic finite element method (TPSFEM) to analysis probability parametars and distribution of structure dynamical eigenvalue is proposed. TPSFEM combines finite element method to structure dynamical eigenvalue with three - parameter method to reliability analysis. TPSFEM not only solves how to process reliability analysis in structure problem, but also improves the analysis precision in reliability. Several examples are given, and the results ascertain that TPSFEM is feasible and effective.

Key words: Dynamics, Finite element method, Reliability, Stochastic, Flexible rack, Joint actuator, Robot, Variable stiffness
