柔性多体系统动力学的并行迭代算法
Parallel Iterative Algorithm Studies of Flexible Multibody System Dynamics
摘要
Abstract
In order to improve the stability and accuracy of multibody system dynamics calculation,the paper focuses on the modeling and algorithm for flexible multibody system dynamics.By using classification algorithm and iterative algorithm,the flexible multibody system dynamics model is solved.The parallel iterative algorithm is accomplished by the waveform relaxation technique and the Runge-Kutta method.In order to reduce the complexity of the calculation and improve the convergence speed of the iterative algorithm,the inner-outer step parallel iterative process has been proposed,and the convergence of the iterative algorithm is further proved,and the error estimate has been accomplished as well.关键词
