摘要：

针对大型液压装备在工作过程中的液压冲击会对设备产生巨大的危害等问题，设计了某大型液压装备的液压冲击装置，对该装置的功能、指标要求进行了介绍，对典型元件进行了计算与选型，并对液压冲击进行了计算，完成了其电气控制系统、测控系统和基于HMI的人机交互系统的设计。以卸荷冲击压力测试工位为例进行了两组试验，试验表明：当系统压力为3 MPa时，开口度为50%时的流量冲击较开口度为100%时大15%左右；当系统压力为5 MPa时却相反，开口度为50%时的流量冲击较开口度为100%时小30%左右。设计的大型液压装备的液压冲击装置实现了对液压冲击的性能参数的分析和测试，这对大型液压装备的液压冲击功能分析、减少液压冲击对设备的影响有着重要的意义。

For the problem that the hydraulic impact of large hydraulic equipment will cause huge harm to equipment during the working process, a hydraulic impact device for a large hydraulic equipment was designed. Then, the functions and index requirements of the device were introduced, and the typical components were calculated and selected. Furthermore, the hydraulic impact was calculated, and the design of its electrical control system, measurement and control system and human-computer interaction system based on HMI was completed. And two sets of tests were carried out by taking the unloading impact pressure test station as an example. The results show that when the system pressure is 3 MPa and the opening degree is 50%, the flow impact is about 15% greater than that when the opening degree is 100%. However, when the pressure is 5 MPa, it is the opposite. When the opening degree is 50%, the flow impact is about 30% less than that when the opening degree is 100%. Thus, the designed hydraulic impact device for a large hydraulic equipment realizes the analysis and test of the performance parameters for hydraulic impact, which is of great significance on the analysis of hydraulic impact function of large hydraulic equipment and reducing the impact of hydraulic impact on the equipment.
