依据曲轴圆角滚压加工工艺过程在ABAUQS中建立了滚压有限元模型,分析了几种不同滚压力作用下的最大残余应力及曲拐变形情况,得出了其随滚压力的变化规律,可为滚压加工时滚压力的选取提供参考并有助于后续的曲轴疲劳寿命分析。
According to crankshaft fillet rolling process, a rolling finite element model was established in ABAUQS. The maximum residual stress and deformation of bell crank under several different rolling forces were analyzed. It provides a reference for the selection of rolling pressure during rolling and contributes to the follow-up crankshaft fatigue life analysis.
