Design method and finite element analysis on refrigeration scroll compressor

摘要

The integrated concurrent engineering approach to the design complex-shaped scroll compressor is presented. A virtual computer integrated design system for the approach is constructed with various commercial software packages. The concurrent engineering combined with information technology is used for the scroll compressor computer-aided design. The advantages and disadvantages of the software used were analyzed. Pro/ENGINEER software is used for the main role in the approach. The finite element analysis technique which carried out in ANSYS is adopted to analyze and describe deflection and stress of actual operation of scroll compressor, which analyze the condition of high stress and strain range. The result is that the stress generally focus on the field where the inside scroll ring of orbiting disc overlaps the shafting bearing hole, with the maximum stress of 97mpa and within promised range.
