ADAMS多体系统建模与动力学方程迭代求解

Modeling of Multi- System and Iteration Solving of Dynamic Equations Basing on ADAMS

基于ADAMS的复杂多体系统建模与动力学方程的迭代求解,是将复杂多体系统分割为一个主子系统和若干辅子系统。主子系统用ADAMS建模并求解。辅子系统由用户自编外部程序建模并求解。依据位移、速度、加速度的协调条件,使主、辅子系统发生联系,利用ADAMS求解器嵌含的迭代过程,实施整个系统的迭代求解。

The modeling of multi-system and iteration solving of dynamic equation is that a complicated multi-system is divided into one host subsystem and some secondary subsystems. Host subsystem is modeled and solved with ADAMS, and secondary subsystem is modeled and solved by user subroutine. According to some conditions of displacement, velocity and acceleration, forces are used to link host and secondary subsystems. Whole iteration solving of system is realized with involved iteration process in ADAMS solver.
