以挖掘机液压缸为研究对象，对液压缸前腔缓冲装置的缓冲动态特性进行研究。主要是基于CFD动网格仿真技术，建立了缓冲结构的Matlab仿真模型和CFD仿真模型，根据已有的液压缸缓冲结构尺寸获得仿真输入条件，仿真得到了液压缸缓冲过程的缓冲压力动态特性。经过与实物测试数据比对，验证了计算方法和数学模型的正确性。

The buffer dynamic behavior of cylinder buffer device is researched, which is uesd in cylinders of excava-tors. The simulation model for Matlab and CFD moving meshes of buffer device are built based on CFD moving meshes simulation technology. Input conditions needed for simulation are got according to the size of the buffer structure and the buffer pressure dynamic behavior is also obtained. The test results show that the calculation method and simulation model are reasonable.
