摘要
车辆液压动力转向系统通过伺服阀控制压力油的方向和流量,把转向盘输入的转角信号转变为车轮的偏转角度输出。在车轮偏转过程中,影响车轮偏转的力主要是地面摩擦力和轮胎的弹性变形力,因而动力转向系统所受干扰力的基本特性是非线性的,文中结合液压系统理论和Simulink控制系统仿真软件,计算并仿真了在非线性干扰力作用下的液压式动力转向系统的动态特性。
Vehicle power steering systems control direction and flow of pressure oil with servo valves,then transfer angular inputs from steering wheels to corner angular outputs of road wheels.During road wheels turning,friction forces from ground and elastic forces of tire are the two main resistance force on road wheels,so the basic features of disturbing force on power steering systems are nonlinear.Dynamic characteristic of hydraulic power steering systems under nonlinear disturbing forces is simulated with Simul...
