【摘要】 液压缸是工程机械的执行元件,其故障轻则影响外观和工作效率,重则导致整机停机甚至车毁人亡,因此液压缸故障诊断和寿命预测是目前和未来一段时间研究的重要方向。该文首先简述现有故障诊断和寿命预测研究现状,然后针对工程机械液压缸故障诊断和寿命预测进行浅谈,并对应用前景进行展望。更多还原

【Abstract】 The hydraulic cylinder is the executive component of construction machinery. Its failure will affect the appearance and working efficiency,and even cause the whole machine to shut down or even the vehicle to be destroyed. Therefore,the fault diagnosis and life prediction of the hydraulic cylinder is an important research direction at present and in the future. In this paper,the current situation of fault diagnosis and life prediction is briefly introduced,and then,the fault diagnosis and life prediction of hydraulic cylinder of Construction Machinery are discussed,and the application prospect is prospected..更多还原
