摘　　要：通过对转向系统的数学模型、转向油缸工作腔流动连续方程及转向油缸动力平衡方程进行拉氏变换,得出了负荷传感全液压转向系统的传递函数。在此基础上,对由输入信号和外加负载信号引起的系统稳态误差进行了分析,并得出影响系统稳态误差的主要参数,为负荷传感型全液压转向系统的设计与改进提供理论依据。In this paper, Laplace transformed the mathematical model of the steering system, the flow continuity equation of steering cylinder working chamber, and the dynamic equilibrium equations of steering cylinder, obtained the transfer function of load-sensing hydraulic steering system. On this basis, the system steady-state error caused by the input signal and the load interference signals are further analyzed, and the main parameters affecting the steady-state error are analyzed. It provides theoretical basis for design and improvement of hydraulic steering system of load-sensing type.
