摘要

应用单轴及多轴疲劳寿命预测的Von Mises等效应变模型和临界平面模型对某两级涡轮盘传动臂销钉孔的疲劳寿命进行预测.组装和调试了全尺寸两级涡轮盘联合试验件

在旋转试验器上完成了低循环疲劳试验

得到两级涡轮盘传动臂销钉孔试验失效寿命.预测寿命与试验寿命对比分析显示单轴和Von Mises等效应变模型预测误差较大;临界平面模型误差较小

尤其是拉伸型失效SWT(Smith-Watson-Topper)模型误差为9.26%.

Abstract

The fatigue life of a two-stage turbine disk transmission arm pin hole was predicted by the models of uniaxial

Von Mises strain and critical plane.A full-scale two-stage turbine disk was fabricated and debugged

and then tested for LCF(low cycle fatigue).The predicted life was compared with the life evaluated by fatigue test of real turbine disk

and the result shows that the predicted errors of the critical plane model are less than those of the uniaxial model and the Von Mises strain model

especially the error of SWT(Smith-Watson-Topper)model is 9.26%.
