Performance Calculation and Test Analysis of PDM Lining with Super-Elastic Constitutive Model

Abstract:

Based on performance comparison of PDM equidistant and conventional elastomer lining, the impacts on the PDM performance were presented with different equidistant lining thickness. According to the Mooney-Rivlin two-parameter model and the Poisson radio equaling to 0.5, the elastomer is incompressible during the calculation and its relational material parameters such as elastic modulus and shear modulus were determined. The PDM stator and rotor curve equations were established according to hypocycloid theory. The lobe configuration is 3:4, the performance comparisons were investigated including deformation and Mises stress between conventional and equidistant elastomer lining of PDM with contact model. The test data pointed out torque, rotation speed, volumetric and overall efficiency variation results with the motor pressure difference changing from 1.93MPa to 5.90MPa. The presented results could be used for PDM design optimization and performance improvement.
