Strength Calculation Method and Parametric Method of the Turbine Shaft

The working principle of turbodrill is discussed in this paper, through discussing the structural characteristics of the turbine shaft, it is pointed out that the part where minimum axis diameter of the turbine shaft is, the hollow area of the turbine shaft, and the hollow place where is the thread at the bottom of the turbine shaft are the three most dangerous parts. With the structure of the turbine shaft of 195mm turbodrill as an example, the strength calculation methods and calculation results of the three most dangerous parts are given. Through comparative analysis on various advanced international parametric design platform, the SolidWorks is chosen as a basic platform for parameterization, this paper puts forward the parametric method of 195mm turbine shaft and the series design of turbine shaft have been achieved. The strength calculation method and parametric method of the turbine shaft have been developed and used in the series design in Yangtze university of China.
