Structural dynamic analysis of the orbiting scroll wrap in the scroll compressor
Frontiers in Energy, 2013A deep analysis of orbiting scroll wraps was conducted in this paper by using ANSYS and SolidWorks. Through the modal analysis, the involute of the circle profile orbiting scroll wrap demonstrated a large span in natural frequencies, which led to more superiority in avoiding structural resonances.

Scroll profiles in scroll compressors: General criteria and error sensitivity
International Journal of Refrigeration, 2013Abstract General criteria for scroll profiles that include the evolute, orbiting movement, differential, and integrative conditions are proposed. The profile error sensitivity is defined based on the composite meshing error and meshing clearances of the scroll profiles.

Scroll Compressor Wall Strength Improvement
SAE Technical Paper Series, 1996<div class="htmlview paragraph">Scroll wall strength is of critical importance to compressor reliability and durability. This is most critical at the center portion of the scroll wall as it is exposed to the highest working gas pressure in the A/C system as well as to high discharge gas temperatures.</div> <div class="htmlview paragraph"&

The Strength Model of Small Parameter Scroll Wrap in a Scroll Compressor
Advanced Materials Research, 2011The paper analyzed the pressures and the temperatures in compression chambers for calculation of bending fatigue strength , and a strength model is proposed. For the small parameter scroll wraps, the pressure loads are of π-region pressures which have a normal angle interval of π, the number of acting regions for pressure loads is equal to the number ...
