摘要
研究高速履带车辆越障过程的动力学响应,以多刚体动力学理论为基础对高速履带车辆悬挂系统建立动力学模型。模型中特别考虑了履带的影响,将其抽象为履带环绕惯性力和履带张力之和。通过Matlab/SimuLink环境对所建模型进行了计算机仿真,并将仿真结果与实车实验结果进行对比分析,结果表明了模型的可信度。本文所建模型和建模采用的方法对履带车辆的系统设计和动力学分析具有积极的作用。
The dynamic response of the suspension system for high-speed tracked vehicle across obstacle was studied in this paper. Applying the theory of multibody dynamics to the suspension system, the dynamic model of the system was established and the planar motion equations were set up. The track loop contribution to the equations was carefully considered. tension of the track loop acting on Physically, it can be equivalent to the the chassis and roadwheels. Simulation forces composed of inertial force and program was developed using the tool of Matlab/SimuLink. It is proved that the simulation model and analysis method are acceptable from the com- parison of the simulation results with on-site test results, which can be used for the suspension system design and dynamic analysis of the armored vehicle.
