摘　　要：随着科技步伐的不断加快,连杆零件在机械领域中得到了广泛应用。连杆零件的工艺特点可归结为3个方面:改善了连杆的加工工艺,连杆两端的组成为斜面和窄平面,带止口斜结合面。连杆的疲劳性能试验有2种方法:一是发动机台架试验,试验结果准确可靠;二是通过高频疲劳试验机的疲劳试验,这种方法时间短、费用低,但不能完全模拟连杆在实际工作条件下的受力状态。With the accelerating pace of technology,connecting rod parts in the mechanical field have been widely used.The process of connecting rod part characteristics can be attributed to three areas： improving the process of connecting rod,rod ends and narrow the composition of the slant plane,with only the mouth oblique joint surface.Fatigue behavior of the connecting rod are 2 ways： First,the engine test bed,test results are accurate and reliable;the second is through the high-frequency fatigue testing machine fatigue test,this method time is short,low cost,but it can not simulate link under actual working conditions in the stress state.
