摘要: 采用有限元法,结合轧机实际工作情况,对轧机滑块式万向联轴器进行整体建模计算,分析出主要零件的危险部位,并找出扁头断裂的原因。在此基础上建立滑块式万向联轴器有限元参数化模型,依据等强度原则并考虑叉头成本高等因素对联轴器进行优化。优化后在叉头有足够疲劳强度前提下,扁头危险部位最大主应力降低了19.21%,疲劳寿命增加了4.3倍。优化结果表明:滑块式万向联轴器的整体承载能力和工作寿命得到了提高,从而实现了对联轴器的结构优化设计。Abstract: Using the finite element method and considering the actual working condition,the system model for cal-culating the rolling mill slider typed universal coupling system was implemented and the dangerous position of the key parts were analyzed and the reason of the flat head fracture was found out. The finite element parametric model for the slider typed universal coupling system was built and optimized on the basis of the equal}trength principle,and high}ost factor of fork head was considered. The optimized stress in the dangerous position of the flat head de-creases 19.21%,the optimal fatigue life of the flat head increases 4. 3 times and the strength of the fork head is al-so enough. The optimal results show that the whole carrying capacity and working life of the slider typed universalcoupling system were improved,so as to realize structural optimization design of the coupling system.
