| Abstract: | Based on the large finite element software ANSYS, the paper takes 3-dimensions finite element analysis on diaphragm pump crankshaft, determines location of the crack, gets the value of stress intensi- ty factor of crack in the crankshaft by use of ANSYS software of sub model method. This could be provide relevant fatigue fracture parameters and technical support for predicting bearing capacity of the crack in the crankshaft, establishing the standard for waste. |
