英文摘要	On the basis of in-depth study of scroll compressor profile construction, a new method for constructing scroll profiles using Frenet moving frame was proposed, a new type of variable wall thickness scroll profile was constructed by this method. The basic geometrical theory of the profile was established and the working chamber volume was also derived. On this basis, four performance indexes including compression ratio, area utilization coefficient, axial gas force and tangential gas force were introduced to evaluate its performance. The results show that under the same geometrical parameters, the newly constructed variable wall thickness scroll profiles have better performance than traditional variable wall thickness scroll profile. Not only the compression ratio and the area utilization coefficient are increased by 7.15% and 4.84% respectively, but also the axial gas force and tangential gas force are also significantly smaller. It can be seen that the use of this variable wall thickness scroll profile helps to further improve the performance of the scroll compressor. © 2020, Jilin University Press. All right reserved.
