Abstract：In order to reduce the force produced by the hydraulic cylinder pressure, in the discharging process, acting on crankshaft to reduce its load and improve the fatigue life of crankshaft, the dimensionless method was used to analyze the evaluation factors related to strength such as crankshaft torque, bending moment and calculation stress, and put forward the optimization method of the crank epoch angle arrangement. And finally, the two optimal of 120 schemes are selected quickly and accurately, which have the best strength of crankshaft and minimize the periodic fluctuation of crankshaft torque and bending moment. Besides, the two schemes can reduce the force and vibration of crankshaft, enhance the structure strength of the dynamic end effectively and improve the reliability of the pump design. And the two schemes proposed are in good agreement with the scheme recommended by "Design of Reciprocating Pump" and adopted by the existing quintuple pump products at home and abroad, which verifies the correctness and feasibility of the design method.
