摘　　要：双定子单作用液压马达有内外马达分别单独工作、内外马达联合工作、内外马达差动工作4种工况,分析了不同工况下转子的受力状况及奇、偶叶片数对转子受力的影响,推导出了各工况下转子受力的表达式,同时根据液压马达样机参数采用MATLAB对转子受力情况进行了仿真。结果表明:转子在4种不同受力状态下所受径向力都在一定范围内做周期性的变化,与传统叶片马达相比,双定子马达转子径向受力较好,且奇数叶片时的转子受力状态更好,为双定子单作用液压马达变量机构的设计奠定了理论基础。Single-acting double-stator motor has four operating states,including inner or outer motor working alone,inner and outer motor united working and differential operating states.Through the calculation of the hydraulic force acting on the rotor in different operating states,the formula of acting force is acquired,the effect of the vane number,which is odd or even,on the acting force is considered.The simulation according to the prototype was carried out using MATLAB.The results show that the rotor radial force varies periodically within a certain range under four strained conditions.Compared with that of the classical vane pumps,the strained conditions of the rotor of single-acting double-stator are better.This study may provide reference for the design of the variable displacement mechanism for single-acting double-stator hydraulic motors.
