摘　　要：利用动力学仿真软件建立了某多轴转向特种车辆的多体动力学模型。对虚拟样车进行了转向盘角阶跃输入性能、蛇行性能等操纵稳定性能试验仿真研究,从中分析普通车辆操纵稳定性评价指标对该三轴特种车辆评价的局限性,对影响操纵稳定性的主要参数值进行了改进。The mutibody dynamics model of multi-axle steering vehicle was built in ADAMS software. The handling stability tests of virtual prototype,such as the steering wheel angle step input test,the snake formation test are simulated. This paper analyzes the limitation of evaluation index of handling stability of common vehicle, points out the defects of existing evaluation index. The most important factor which affects the handling stability of this vehicle is optimized.
