Analysis of Finite Element about Crankshaft’s Stress of Emulsion Pump

The paper focuses on crankshaft the whole cran ks haft of emulsion pump was analyzed with finite element software of ansys5 7,and a method was presented to orientate the dangerous phase and dangerous point of multi-turning crankshaft, and to analyze the fatigue strength.The aims are attai red to optimize the crankshaft structure and improve the design standard of pump .
