| 摘 要： | 为了测量35 MPa高压轴向变量柱塞泵滑靴副的油膜性能参数，需研制一套滑靴副性能测试液压系统。针对35 MPa的高压工作环境，设计出了一种高压轴向变量柱塞泵滑靴副性能测试液压系统，并建立了其AMESim仿真模型。通过仿真分析，得知该液压系统的卸压能满足工作要求，其卸荷性能良好，而且无论是卸压还是卸荷过程，液压冲击均得到有效的抑制，因而，该液压系统能够满足泵在35 MPa高压工况下平稳运行的要求，从而为提高35 MPa高压轴向变量柱塞泵滑靴副的油膜性能提供了前提保障。

| Abstract: | In order to measure the oil film performance parameters of the slipper pair in an axial piston pump of 35 MPa, a hydraulic system for performance test of the slipper pair needs to be developed. Aimed at the working environment of 35 MPa, a hydraulic system for performance test of the slipper pair in the high pressure axial piston pump is designed, and its AMESim simulation model is built. According to the simulation analysis, the following results are acquired: the pressure relief of the hydraulic system can meet the working demand, and its unloading performance is excellent; in addition, for both the pressure relief course and the unloading course, the hydraulic impacts are all restrained effectively. Therefore, the hydraulic system can satisfy the stable running demand of the axial piston pump under 35 MPa, which thus can provides a premise and a guarantee for revealing oil film performances of slipper pair in the axial piston pump of 35 MPa. |
