摘　　要：针对工程机械液压缸内外泄漏故障诊断中故障判据的提取问题,介绍了一种通过监测工程机械液压缸压力和位移信号的模拟实验方法。通过在不同泄漏孔径、不同系统压力、不同系统流量和不同负载情况下的模拟实验,为工程机械液压缸泄漏故障诊断提供有效的判据,具有实际的工程意义。Internal and external leakage is an important factor of construction machinery hydraulic cylinder reliability. Aiming at obtaining the fault criterion of internal and external leakage for con- struction machinery hydraulic cylinder, this paper introduces an experimental research method by monitoring pressure and displacement signal of construction machinery hydraulic cylinder. Through experiments under different orifice size of leakage, different pressure of system, differ- ent flow of system, and different load, an effective basis is provided for fault diagnosis of con- struction machinery hydraulic cylinder internal and external leakage, which will have practical en- gineering significance.
