摘要
以有限元法为基础,在建立搅拌轴有限元力学模型的基础上,先借助有限元软件ANSYS静力分析找出搅拌轴上的危险点,再通过ANSYS-Fatigue模块对这些点进行疲劳寿命分析。通过对危险点螺棱与轴的过渡部分进行疲劳寿命分析,得到疲劳累积系数0.6,表明该搅拌轴在使用年限内满足疲劳强度要求。
The finite element model of the stirring kneader shaft was built based on finite element method. Then the ANSYS software was adopted for the static strength analysis of the stirring kneader shaft, and the dangerous points were found. Using these data, a finite element fatigue analysis was performed by ANSYS-Fatigue module. The results showed that：the cumulative fatigue damage coefficient is 0. 6,and the new stirring kneader shaft is able to meet fatigue requirement during the whole service life.
