The structural strength and fatigue failure of the transmission shaft in the lifting box are analyzed. The general steps of structural strength and fatigue analysis are given. The role of the finite element method in fatigue analysis is also illustrated. Through the analysis of the input shaft of the lifting box, the analysis and checking of the parts by the finite element software and the fatigue analysis software are introduced, and the calculation and analysis flow of the common parts are given.
