| 摘 要： | 热和离心力变化是引起燃气轮机高压涡轮叶顶间隙变化的重要因素,也是转子设计和强度计算中考虑的基本点之一.为了便于进一步研究叶顶间隙变化规律及对轮盘和叶片进行强度计算,本文建立了在热和离心力作用下燃气轮机高压涡轮转子的径向变形模型.定性分析和定量计算了不同工况下热和离心力分别对叶片、轮盘径向变形的影响,以及两者共同作用下的...

| Abstract: | The heat and centrifugal change is an important factor of causing the variety of HPT tip clearance of gas turbine engine.It is also one of the key factors of rotor design and strength calculation.In order to investigate the variety of tip clearance and calculate the strength of disk and blade,the rotor radial elongations model was established.The effects of the centrifugal and heat on rotor radial elongations at different states were qualitatively analysed and quantitatively calculated.The results showed th... |
