双定子异形滑块液压马达角速度不均匀性研究

基于实际工况需要不同的转速和转矩,设计了通过改变进出油口可以实现多种转速和转矩的系列双定子马达。阐述了双定子异形滑块液压马达优点。通过数学公式推导和Matlab仿真分别探讨了1个马达单独工作和2个马达同时工作时不同滑块数下角速度的不均匀性。结果表明,奇数滑块马达输出的瞬时角速度幅值比偶数滑块马达的大,但是角速度的不均匀性比偶数滑块马达小得多。

Uniformity of Double Stator Alien Slider Hydraulic Motor

To meet the needs of different working conditions, a double-stator multi-motors was designed. Double-stator single-acting multi-motors was one of double-stator multi-motors. 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 torque and the number of sliders were obtained. Meanwhile, the results show that the lag angle can influence torque pulsation when outer motor and inner motor work at the same time and differential connection. It turns out that the uniformity of angular velocity is smaller when the number of alien slider is odd, while the amplitude of angular velocity is a little larger than the motor whose number of sliders is even. This research work lays a theoretical foundation for the design of double-stator single-acting multi-motors.
