摘　　要：以某多轴重型高机动越野车辆为平台,设计了一种多模式电液转向系统。多种转向模式的设计、完善的控制策略,以及后桥转向角度的匹配,可以同时满足高速车辆的通过性、操纵稳定性与行驶安全性要求。通过实车试验验证,后桥转向角度控制精度较高,实现车辆的同步转向动作,能够满足实际使用需求。其设计正确、系统可靠,便于实现工程应用。A multi-mode electro-hydraulic steering system was designed based on a multi-axle heavy duty off-road vehicle with high mobility. Due to the multi-mode steering,the reliable controlling strategy and the good matching of steering angle of the rear axle,the requirements of high speed vehicle passability,steering stability and driving safety could be achieved. The vehicle test results verify that the steering system can accurately control the steering angle of the rear axle so that the front and rear axles can steer synchronously to meet the practical needs. This well-designed and reliable steering system can be applied for engineering applications.
