摘　　要：阐述了采用负载敏感技术的自行走全液压载重车转向系统的设计,使用AMESim和MATLAB软件对转向系统进行了联合仿真,分析了液压系统的动态特性,采用带死区的PID控制策略。仿真结果表明,与常规PID控制相比,带死区的PID控制对载重车转向系统的控制效果更好,通过与现场试验所得数据相比较,仿真曲线与实测曲线基本吻合,验证了仿真模型的正确性和控制策略的可行性。A steering system with load sensing technology for self-propelled hydraulic transporter was designed. To research the dynamic performance of the system, a co-simulation was carried out using the AMESim and MATLAB software. A PID controller with dead zone was adopted, and the simulation results shows that the PID controller with dead zone can make the system achieve better working behavior than the normal PID controller. Comparison of the test data and simulation result proved the validity of the simulation ...
