摘要 针对涡轮叶片考核部位的寿命问题,介绍了DD6单晶涡轮叶片热机疲劳试验方法。通过设计感应线圈进行高频感应加热,实现某一工作状态下涡轮叶片考核截面温度场模拟,同时使用U型铁氧体精细调节温差;通过设计的二位移调节机构控制拉伸载荷,实现涡轮叶片考核截面由离心载荷和气动载荷引起的应力场模拟。在保证内冷空气流量的条件下,进行了DD6单晶涡轮叶片热机疲劳试验,实现了涡轮叶片寿命预测方法的试验验证,同时为工程设计提供了试验依据。 Aiming at the life problem of turbine blade, the test method of the thermal-mechanical fatigue of DD6 single crystal turbine blade was introduced. The simulation of section temperature field under some operating state was controlled by the way of high frequency induction heating, which can be adjusted by the "U" type ferrite. While the simulation of stress distribution under the centrifugal and aerodynamic load was controlled by the tension load, which can be adjusted by the two displacements tuning-up framework. The thermal-mechanical fatigue test was carried out while keeping the cool air flux sufficient. It not only verified the life prediction method of turbine blade but also provided reference for engineering design.
