Abstract：Based on the geometry and motion characteristics of hydraulic end in eccentric and squirmy rotor pump, the stress and restriction condition of rotor during the squirm process were analyzed. According to the design parameters of eccentric and squirmy rotor pump, the load and restriction condition at six operating points were calculated and analyzed. A three dimensional model of rotor was built based on ANSYS, and analyzed with hexahedral SWEEP mesh method. Furthermore, a numerical simulation for Polyoxymethylene(Pom) rotor′s intensity and stiffness was carried out by using quasi dynamic model method, and the stress and strain data of the rotor at six operating points were derived. The results of numerical simulation show that the maximum stress of the rotor with Pom material is far less than the allowable value, and both the stress and strain of the rotor meet the demands. The results provide a basis for reliability design of eccentric and squirmy rotor pump.
