摘要
由于缺乏相关的试验研究与理论指导,目前国内在开发全液压装载机方面发展缓慢。文中结合浙江省重大科技专项研发的HT25J型全液压装载机,对液压传动装载机的液压行驶驱动系统进行设计,并详细阐述了车辆具体行走实现原理;建立了液压系统各环节数学模型,根据系统整体传递函数方框图建立了Simulink仿真模型;并采用模糊PID控制器对系统稳定性进行校正,使整个液压行驶系统具备较好的响应性能及抗干扰能力,为国内全液压装载机的设计开发寻求一种理论依据。
At present, for lack of correlation theories, domestic hydraulic transmission loader development lags behind. This dissertation is based on the hydraulic transmission loader HT25J which is developed through a major science and technology projects of Zhejiang province. The hydraulic system of the loader＇s walking device system was designed. The movement principle of the driving system is discussed in detail. The transfer functions of open-loop and closed loop of the whole hydraulic walking system was derived by building the mathematical models of each link of hydraulic walking transmission system. The simulink model was established according to the transfer function block diagram. The fuzzy PID controller was design to calibrating the stability of the system, and making the whole hydraulic driving system has a better dynamic performance and anti-jamming ability.
