摘要：

为研究液压激振系统中高频交变压力下先导式溢流阀的响应特性，建立了先导式溢流阀数学模型和AMEsim仿真模型，仿真研究了高频交变压力下先导式溢流阀开启情况，并进行试验对比研究。仿真结果表明：交变压力下先导式溢流阀主阀口存在异常开启现象，增大了系统能量损失；主阀口异常开启量随交变压力幅值增大而增大；当交变压力频率达到200 Hz时，溢流阀主阀口未出现异常开启。试验结果与仿真结果基本吻合。研究结果对高频交变压力下先导式溢流阀的使用有重要的理论指导意义和实际工程意义。

Abstract:

In order to study the response characteristics of pilot relief valve under high frequency alternating pressure in hydraulic excitation system, a mathematical model of pilot relief valve and AMEsim simulation model were established. The opening of pilot relief valve under high frequency alternating pressure was simulated and the simulation results were compared with experiment. The simulation results showed that the main valve port of the pilot relief valve opened abnormally under the alternating pressure and increased the energy loss of the system. The abnormal opening of the main valve port increased with the increase of the alternating pressure amplitude. When the alternating pressure frequency reached 200 Hz, the main valve port of the relief valve would not abnormally open. The experimental results were basically same with the theoretical analysis. It has important theoretical and practical significance for the pilot relief valve to be used under high frequency alternating pressure.
Key words: high frequency alternating pressure    pilot relief valve    building pressure rate    opening of main valve port
