Numerical Solution for Stiff Dynamic Equations of Flexible Multibody System
Numerical Solution for Stiff Dynamic Equations of Flexible Multibody System
摘要
Abstract
A nonlinear numerical integration method, based on forward and backward Euler integration methods, is proposed for solving the stiff dynamic equations of a flexible multibody system, which are transformed from the second order to the first order by adop- ring state variables. This method is of A0 stability and infinity stability. The numerical solutions violating the constraint equations are corrected by Blajer's modification approach. Simulation results of a slider-crank mechanism by the proposed method are in good a- greement with ones from other literature.关键词
