Load Model of Scroll Wrap for Calculation of Bending Fatigue Strength

Abstract:

For calculation of bending fatigue strength of scroll wraps, the pressure loads and temperatures in compression chambers based on general profile theory are analyzed, and a load model including the pressure loads the temperatures is proposed. For the scroll wraps, their load model for bending fatigue strength includes the pressure loads and the temperatures. Their pressure loads can be simplified on the mid-areas and its temperatures are equal to the temperatures of the mid-areas. The pressure loads are of π normal angle region inner pressure load which have an interval of π normal angle, the number of regions of pressure load is equal to the number of scroll compression chamber pairs. The discharge angle has significant effect on bending fatigue strength of scroll wraps and the stability of scroll compressor.
