双定子单作用液压马达转矩脉动研究

Analysis of Torque Pulsation for Double-stator Single-acting Multi-motors

摘要:

为了解双定子单作用液压马达的性能，在探讨双定子单作用液压马达理论排量和理论转矩的基础上，分析了不同滑块数对液压马达转矩脉动的影响，得出液压马达滑块数与转矩脉动的数学关系式。结果表明，滑块个数为奇数的液压马达的转矩脉动小，进一步推导出滞后角对液压马达差动连接和内、外马达同时工作时的转矩脉动影响。

Abstract:

In order to realize the performance of motor, the influence of torque pulsation by different number of slider was studied based on the analysis of the theoretical displacement and theoretical torque of double-stator single-acting multi-motors. Through the analysis, mathematical expressions of the motors torque and the number of sliders were obtained. Meanwhile, the results show that lag angle could influence torque pulsation when outer motor and inner motor work at the same time and differential connections. This research work laid a theoretical foundation for the design of double-stator single-acting multi-motors. 
