摘　　要：应用ADAMS软件对某车辆的前悬架运动学特性进行了仿真分析,揭示了运动特性参数在悬架运动过程中的变化规律,对导向机构存在的问题进行了优化计算,优化后轮距和前轮侧向滑移量都在理想的范围变动。为研究悬架对车辆行驶稳定性的影响,提出了悬架阻尼神经网络PID控制方法,对车辆实行横摆稳定性闭环控制。针对单移线和阶跃转向两种典型工况,应用MATLAB软件进行了仿真。结果表明,通过悬架阻尼来控制车辆侧偏运动,使左右车轮的载荷转移明显减小,从而能有效抑制车辆的过度转向特性。The kinematic characteristic of a vehicle front suspension was simulated analyzed by us-ing ADAMS,the change regularity of the kinematic characteristic parameters was uncovered in the process of the suspension motion,and the existent problem of the guiding mechanism was optimized and calculated.The results show that the wheel-center-distance and front wheel side slippage are still within the ideal ranges after optimization.In order to research the impact of the suspension on driving stability the suspen-sion damping Neural Network PID control technique was proposed,to make the closed-loop control of the steering yaw stability.The single lane steering and step steering working condition were simulated by MAT-LAB.The results show that the variation of suspension damping can control cornering property and obviously reduce the load shift of the front wheel,and the vehicle over-steering behavior is restrained effectively.
