摘　　要：考虑到液压支架密封件在实际工作时,承受超高压强的同时伴随有压力载荷的波动。在现有液压支架立柱千斤顶密封件性能检测试验台的基础上,设计出具有冲击加载功能的性能检测试验台,模拟密封件的现场工作受力情况。该试验台加载最高压力可达60 MPa,更贴近实际生产时液压支架的工作情况。In consideration of that the seals of hydraulic support sustain super high pressure accompanied by fluctuation in actual working conditions, a test rig has been designed on the basis of existing one for post and cylinder of hydraulic support. The rig serves the function of impact loading to simulate the working condition of the seals in site. The max loading pressure of the rig can be 60 MPa, which is more close to the actual work condition of the hydraulic support.
