摘要：
In order to solve the problem of optimal compression characteristic in the traditional variable cross-section scroll profiles, a method of constructing profiles based on Frenet frame was proposed. Variable cross-section scroll profiles formed by base circle involute with different radius of base circle were constructed by using the method, the basic geometrical theory of the profile was established and the working chamber volume was also derived. Then three performance indexes, displacement volume, compression ratio and area utilization coefficient, were introduced to evaluate its performance. The results show that the newly constructed variable cross-section scroll profiles have better performance than traditional variable cross-section scroll profiles, and the displacement volume, compression ratio and area utilization coefficient are improved 9.12%, 16.44% and 9.06% respectively. © 2019, Editorial Board of Journal of Huazhong University of Science and Technology.
