用常规方法和有限元法对某发动机气冷涡轮转子叶片的静强度进行了具体的计算分析,为该机如期上高空台试验提供了强度数据。试验证明,本文的计算分析结果是令人满意的。
The static strength of an air-cooled turbine rotor blade of aeroengine was calculated and analyzed by the conventional method and the finite element method, which provided the intensity data for the aircraft on the high altitude bench test. Experiments prove that the calculation and analysis results in this paper are satisfactory.
