Temperature distribution simulation analysis method of air turbine starter

The invention relates to a temperature distribution simulation analysis method of an air turbine starter, which is used for carrying out temperature distribution analysis on the air turbine starter by using a temperature distribution analysis result of a magnetic gear reducer, and belongs to the technical field of aero-engine starting. The problems of low precision and accuracy of temperature distribution analysis of the air turbine starter in the prior art are solved. According to the temperature distribution simulation analysis method, the magnetic loss and the wind friction loss of the magnetic reducer are considered, temperature distribution analysis of single coupling and comprehensive consideration of various influence factors is carried out in combination with the temperature rise inlet condition caused by turbine end air inlet, meanwhile, the influence of air gap thickness parameters is introduced, and the temperature distribution simulation analysis method can be used for realizing the temperature di
