摘　　要：针对静态信号负荷传感全液压转向系统在转向初期存在的压力振摆问题,分析负荷传感全液压转向系统原理,并根据实际工况建立其AMESim仿真模型,对不同输入条件下的压力响应进行定量仿真分析。仿真结果表明,车体转动惯量的大小以及LS管线长度对压力响应有重要影响。适当减少车体转动惯量以及合理设置LS管线长度可以提高系统的响应速度和稳定性,为负荷传感全液压转向系统压力振摆问题的解决提供参考。Focus on problem of pressure pendulum at early stage of steering in load sensing full hydraulic steering system,working principlesof load sensing full hydraulic steering systems is analyzed.And the AMESim simulation model is built based on its actual working conditions.The pressure responses under different input conditions are quantitatively investigated.Simulation results show that the size of momentinertia of vehicle body and the length of LS line has great influence on the dynamic response of pressure.And reducing moment inertiaof vehicle body as well as adjusting length of LS line appropriately can improve the response speed and stability of the system,which providesome guidance for the solving of pressure pendulum in load sensing full hydraulic steering system.
