履带车辆的履带模型与分析

由于履带的存在，使得履带车辆成为一个十分复杂的动力学系统。目前对履带车辆的研究越来越多的运用仿真的方法。履带模型是履带车辆建模与仿真过程中的关键问题。本文分析了履带-地面-负重轮之间的关系，阐述了两种履带模型的建模原理，并将其分别用于基于DADS的履带车辆平稳性模型当中。比较了履带车辆行驶过程中履带对平稳性能的影响，并对产生影响的原因进行了解释。本文的结论有助于运用仿真方法研究履带车辆的性能．

Track Model and Analysis of High-speed Tracked Vehicles

Tracked vehicles represent a complex dynamical system primarily due to the presence of the track. Nowadays research to the tracked vehicles more and more resorts to simulation. Track model is a key issue in the modeling and simulation of tracked vehicles. The principle of two types of track models is presented through systematic consideration of track dynamics, and track-terrain-roadwheel interactions. And a ride model of tracked vehicles based on software platform DADS is established and the ride response of tracked vehicles is evaluated and compared in conjunction with different track models. Also the reasons of different responses between two tracks are illustrated. The results of the study are utilized to study the properties of tracked vehicle by simulation.
