摘　　要：独特的工作特征如挖掘、回转、行走等极易引起挖掘机的液压冲击。笔者在分析挖掘机工况的基础上探讨了挖掘机液压冲击的成因,利用能量守恒定律推出冲击压力表达式并给出试验验证。There are many special factors that easily bring hydraulic impact in excavator, such as digging, swing and travel etc. The causes of hydraulic impact were discussed based on the work condition analysis in excavator and the methods of computing in view of the law of energy conservation were provided. A trial was made to testify the methods of computing.

关 键 词：挖掘机 液压冲击
