Résumé

In the study, CAE analysis was actively applied to secure the high reliability of the main components and to improve the performance of compressor. A scroll compressor which separates the high pressure from the low pressure by a fixed scroll was developed. The deflection of the fixed scroll during shrink-fit process of a top cap was minimized by using CAE deformation analysis. The validity of the analytical results was verified by comparing experimental results. Furthermore, the optimal contact force between the outer wall surface of a fixed scroll and the inner surface of a top-cap was calculated analyzed by CAE analysis with the change of top-cap thickness in order to prevent the leakage between two surfaces. The thermal and pressurized deflection of the fixed and orbiting scrolls was analyzed on the whole operation envelope to select the optimum assembling clearance.
