The result of the calculation for tip clearance is reasonable when it is compared with theory. two ways are put forward for convention of dimension of the turbine components from high temperature to low one, which is related with tip clearance, a simple example is used to illuminate that the two ways are useful, using the method of design optimization, axiisk and a blade of a certain turhine is analysed, it showes that the method of design optimization is feasible to be used for convertion of dimension of the turbine components. finally, ansys software is used to analyzed the variation of tip clearance with the method of cyclic symmetry analysis when engine works under the conditions of temperature and rotational speed, am using a new method to deal with thermal contact resistance in the calculation
本文完善了計算渦輪葉尖間隙的簡化演算法程序，增加了程序的計算功能，並將其應用於某高壓渦輪進行葉尖間隙分析，所得結果與理論結果進行了對比，得出修改後的程序用於葉尖間隙計算是合理的；同時提出了與葉尖間隙相關的渦輪典型部件的冷、熱態的尺寸兩種換算方法，使用優化設計的方法進行了實例分析，說明了所提出的計算方法是可行的；最後應用ansys有限元軟體利用循環對稱的方法分析了某型發動機高壓渦輪在溫度場及離心力作用下的葉尖間隙在發動機工作過程中變化情況，並分析了計算中的接觸熱阻的處理問題。 -
