摘要

针对单晶空心气冷涡轮转子叶片的热机械疲劳(TMF)试验要求

建立了涡轮叶片热机械疲劳试验系统

包括加载、加热、气冷、水冷和控制等5个子系统.试验结果表明:该系统能够同时模拟服役条件下单晶涡轮叶片考核截面的应力场、温度场、气冷过程以及应力/温度谱等.利用该试验系统进行了单晶涡轮叶片考核截面的热机械疲劳试验

试验结果再现了涡轮叶片在服役状态下的失效模式.基于上述试验结果可以进行涡轮叶片的寿命预测和失效分析.

Abstract

An experimental system including 5 subsystems:the loading

heating

air cooling

water cooling and control subsystems

was constructed to satisfy the requirements of thermo-mechanical fatigue (TMF) experiments of single crystal hollow turbine blades.The TMF experimental system provided evidences that the stress distribution

temperature distribution

air cooling and stress/temperature spectrum on critical section of turbine blades under service conditions could be simulated simultaneously in a laboratory environment.And the TMF experiments were performed on the critical section.The results of the TMF experiments reproduced the failure model of the turbine blades.Based on these results

life prediction and failure analysis could be investigated.
