英文摘要：

The kinetics character of flexible mechanism is nonlinear. For the purpose of kinetic analysis and dynamical reliability analysis of flexible mechanism, a virtual prototype model was built on integrated simulation environment of UG-ANASYS-ADAMS. Methodology of kinetic simulation on the integrated multi-software platform was presented. Monte Carlo （MC） method was applied to generate stochastic variables for dynamical responds analysis. Artificial Neural Network （ANN） was applied in MATLAB for dynamical responses analysis and reduction of time consuming. Statistical distribution of kinematical parameters was yielded from the outputs of ANN and dynamical reliability of kinematical parameters was gained. As an example, a flexible expand mechanism model of space station was employed to test this method. The results prove that this method is available for kinematical analysis and dynamical reliability analysis of complicated flexible mechanism. It has the advantage of high precision and reasonable computational cost.
