Integration of Solid Modelling and FEM Analysis for the Design of Scroll Compressors

Abstract

Abstract This paper presents an integration approach to solid modelling and finite element method (FEM) analysis on the components design of a scroll type of compressors which are becoming popular and widely used in refrigeration and air conditioners. It is time consuming to design and manufacture a scroll compressor since its two key components are complex shaped and high precision requirements. The authors use C++ programming and Pro/ENGINEER to implement the proposed approach and associated design development. Constructive solid geometry (CSG) modelling of two scroll components are created and presented. FEM analysis is used to further consolidate the modelling with respect to force and heat influences, etc. The paper concludes with a discussion on the potential of the proposed approach in mechanical product design.
