轮式装甲车辆不同差速器方案操纵稳定性仿真研究

Simulation Research on Wheeled Armored Vehicle Operating Stability in Different Differential Mechanism Schemes

以某轮式装甲车辆为研究对象,通过建立虚拟样机,使用动力学仿真分析软件按国军标试验规范模拟了其稳态回转性能等相关科目仿真,对不同差速器方案对该车操纵稳定性的影响进行了分析,综合评价了车辆在不同差速器方案下的操纵稳定性,通过相应试验科目结果对比,证明仿真模型正确,仿真结果可信。

Taking a certain wheeled armored vehicle as research object, its steady state steering performances and corresponding subjects were simulated by the established virtual prototype, the dynamic analysis software and the test specifications in GJB test standard. The influence of different differential mechanism schemes on operating stability of the vehicle was analyzed in detail. For different schemes, the operating stability of the vehicle was valued synthetically. The correctness of the simulation model and the credibility of the simulated results were verified by the comparison of the simulated results with the tested ones for corresponding subjects.
