| 摘 要： | 连杆螺栓预紧力对连杆盖和连杆体的接合状态影响较大,为了保证有较好的接触压力,对连杆组件进行有限元数值分析。利用接触算法,重点分析从28～60kN范围内的13种不同的螺栓预紧力对连杆接触面、轴瓦接触面等的平均应力、应变值的变化情况。综合考虑各种情况,最终确定一个合适的螺栓预紧力,为设计人员提供了理论依据。

| Abstract: | The bolt pretightening force is important to bonding state between a connecting rod cap and a connecting rod body. The connecting rod assembly was analyzed by FEA to ensure an appropriate bolt pretightening force. A contacting calculation was used to analyze the effect of the pretightening force on mean stress and strain of connecting rod interface and bearing interface by applying 13 different kinds of tightening force from 28 kN to 60 kN. In consideration of all situations, a final appropriate bolt pretightening force was defined. |
