This study analyzes the impacts of vanes on rotor slots by simulating the impacts of two plates in a sliding vane rotary compressor. The Hertzian contact rule and the first order shear deformation plate theory incorporating the shear deformation and the rotary inertia are used to generate a mathematical model. Impact forces are calculated at various times and positions of the vane. Data generated from the model highly correlated with results obtained from ABAQUS software.
