针对转向制动工况的多轴轮式装甲车辆模型与试验验证

Multi-axis Wheeled Armored Vehicle Model for Steering Braking Condition and Experimental Verification

车辆动力学建模是车辆动力学性能仿真分析的关键，动力学模型的准确程度直接影响到仿真结果的准确程度。针对所研究的车辆在转向制动工况下的行驶稳定性，以某三轴轮式装甲车辆为原型，建立了动力学模型，并通过直线制动和角阶跃制动两个试验，间接验证了模型的准确性，为转向制动工况的仿真建立模型基础。

Vehicle dynamics modeling is the key to the vehicle dynamic performance simulation analysis. The accuracy of the dynamic model directly affects the accuracy of the simulation results. Aimed at the stability of the vehicle under the steering braking condition,the dynamical model was established taking a three-axis wheeled armored vehicle as the prototype. And through the straight line braking and angle step braking tests, the accuracy of the model was indirectly verified, which lays a model foundation for simulation of steering braking condition.
