摘要
以转8A型转向架侧架为例,介绍了有限元技术应用于构件疲劳寿命分析的过程。按照"准静态"方法将有限元分析得到的静态应力与实测的载荷时间历程相结合得到模型上各点应力时间历程,结合ZG230 450材料的S N关系进行了结构整体的疲劳寿命计算。有限元分析软件是I DEAS,疲劳寿命分析软件是FE FATIGUE。
Using the side frame of the Z8A bogie as an example, this paper introduces the process of fatigue life analysis of a component based on the finite elements technology. In accordance with the quasistatic method, the stress histories of different points of the model are derived by combining the static stresses and the measured load histories. The fatigue life of the whole component is calculated in combination with the S-N relations of the ZG230-450 material. The finite elements analysis software is I-DEAS, the fatigue analysis software is FE-FATIGUE.
