Title Modeling and Simulation of Tank Multi-body System
Abstract
Tank is a multi-body system with great complexity, the research on it is part of mechanical system dynamics. With the development of multi-body system dynamics theory, simulation analysis of mechanical systems is being greatly enhanced. With the background, some preliminary research into the simulation theory of mechanical systems was done in this paper, and a model was established on virtual prototyping using ADAMS and a CAD software, to describe the tank, especially the track system. Several simulations was done with different road surface, and the vibration situation was got,and the effection of parameters such as torshion’s stiffness and bushing’s stiffness was described. The results were basic for anylysing the effection of stiffness on ride comfort of tank. The work of this paper provided a reference to improving shooting accuracy of tank.

1 绪论
行进间射击精度是坦克系统的一个重要的性能指标，因此如何提高坦克系统行进间射击精度是我国武器研制一直追求的目标。坦克的运动对弹丸起始扰动和射击精度影响较大，坦克系统动力学分析与仿真是提高坦克火炮系统射击精度的重要途径。
