Stress and Deformation Analyses of Twin-Spirals Scroll Plates Based on CAE

On the basis of the elastic mechanics theories, heat transfer theories, and CAE, the non-uniform temperature distribution was studied, Mises stress and deformation distribution of 3D twin-spirals scroll plates was presented. The Mises stress and deformation of scroll plates induced by non-uniform temperature field and gas pressure was investigated. Orbiting and fixed scrolls were engaged with each other and the Maximum Mises stress and deformation of scroll plates analyses were performed under different axial and radial gap at the crank angle that the Maximum compression ratio happens. On the basis of calculated results using CAE, the suitable gap value for twinspirals scroll plates design was presented, which provided useful data for developing the high-performance twinspirals scroll compressor.
