摘　　要：为了减小液压冲击对液压系统的影响,提出了一种以新型双定子泵为动力元件的液压传动系统,在阐述了其工作原理和特点之后,对该新型传动系统换向时的液压冲击进行了理论分析,并采用AMESim软件进行仿真分析。结果表明,该新型回路不但能够实现多种压力和速度的变化,并且换向冲击也比传统的控制回路要小。在很大程度上提高了回路的效率,具有良好的节能效果。A new hydraulic transmission system based on double-stator pumps is proposed in order to reduce the reversing impact or me ny- draulic system. After expounding working principle and characteristics of the system, the hydraulic shock of the new transmission is ana- lyzed. Then a series of simulation analysis are done underAMEsim. The results show that the new circuit will not only be able to achieve a variety of pressure and speed, and the hydraulic is much smaller than the traditional circuit, which greatly improve the efficiency of the cir- cuit and has a good energy saving effect.
