摘　　要：针对某型径向柱塞马达液压缸工作过程中出现的裂纹现象,在Workbench和n Code Design-Life软件中对液压缸进行有限元分析和疲劳可靠性分析。得出该液压缸的疲劳寿命和疲劳损伤云图,确定液压缸的易破坏位置为轴根部,试验验证结果与软件分析相一致。For the phenomenon that cracks appear on a element analysis and fatigue reliability analysis are made certain type cylinder of radial piston motor, the finite to the cylinder by using the workbench software and the nCode Design-Life software. As a result, the fatigue life and fatigue damage nephogram of the cylinder is obtained to determine the position which is easy to damage at the bottom. The test result goes with the software analysis.
