摘要
通过对直列四缸发动机曲轴进行有限元分析,模拟其真实工作条件,计算曲轴在1缸发火时的受力情况,分析最大等效应力和变形,发现最大等效应力值远远小于材料屈服强度,具有优化空间。在此基础上,使用Workbench中自适应优化算法对其进行优化,优化后的曲轴最大等效应力和变形基本不变,质量减少了9.31%,实现了其轻量化设计,为曲轴的结构改进提供了有效的参考。
Through finite element analysis of the inline four-cylinder engine crankshaft,simulating its real working conditions,calculating the crankshaft force at the firing of one cylinder,analysing the maximum equivalent force and deformation.and finding that the maximum equivalent force value is much smaller than the material yield strength,with room for optimisation.On this basic,the crankshaft was optimised using the adaptive optimisation algorithm in workbench.After opyimisation,the maximum equivalent force and deformation of the crankshaft were basically unchanged,and the mass was reduced by 9.31%to achieve its lightweight design,which provides an effective reference for the structural improvement of the crankshaft.
