| 摘 要： | 从液动射流式冲击器活塞冲锤的受力分析入手，建立了活塞冲锤的运动方程，并求出了解析解，编制了液动射流式冲击器计算机辅助设计软件。液动射流式冲击器设计软件的计算结果与室内冲击器试验进行了对比拟合，实测值与计算值吻合的较好，误差小于6％，并通过软件模拟计算得出了各参数变化对冲击器性能参数的影响，为液动射流式冲击器的设计提供了理论依据。

| Abstract: | After analyzing forces exerted on the hammer of a hydraulic percussion tool, the paper develops a motion equation of a piston hammer, gives its analytical answers, and develops its CAD software. Computational results are in good accordance with actual measures with errors less than 6% by lab tests. Affects on percussion properties resulted from working variables are simulated by the soft ware, and provides theoretical foundations for designing a hydraulic percussion tool. |
