摘　　要：对液压动力转向器的转向控制阀进行动力学分析,并且建立了负载压力、负载流量的无因次方程。通过分析转阀特有的非线性,提出了适合转向特性的非线性区间。试验结果表明:基于非线性特性的动力转向器具有很好的转向灵敏度和转向力特性,其对称性分别达到了98.15%和96.37%。The dynamic characteristic of rotary valve of hydraulic power steering gear was analysed, and the non-dimensional equation of loading pressure,loading flow was established. The nonlinear range for steering was put forward based on the specific nonlinear characteristic of rotary valve. The experimental results showed that the power steering gear had good response characteristic and force characteristic and their symmetry characteristics were 98.15% and 96.37% respectively.
