动力转向器阀油槽尺寸和分度误差对压力静特性的影响

Pressure response characteristic of PSG valve influenced by errors of distributing oil slot

根据阀的液压等效桥路模型,首次推导了非对称阀分配油槽存在尺寸和分度误差时的压力静特性的一般公式,定量地分析了这些误差对压力静特性的影响。

According to hydraulic-circuit equivalent bridge model of valve,the universal formula of pressure response characteristic (PRC) of PSG unsymmetrical valve with errors of distributing oil-slot was established firstly.The PRC influenced by the errors was analyzed qualitatively.
