Based on the analysis of the profile of dual-acting vane compressor cylinder, the criterion of judging the advantages and disadvantages of cylinder profile is established, and the principle of cylinder profile generation is proposed. Based on this principle, six cylinder profiles are constructed and their characteristic equations . Analysis of these profiles using the discriminant criterion found that the characteristics of the simple harmonic cylinder profile are superior to those of other profiles. By analyzing the structural parameters of the simple harmonic cylinder line and the relative lift on the profile characteristics and the working chamber volume, the optimum range of 0 is optimized. 27 ~ 0. 35. Finally, the performance of vane compressor and vortex compressor with simple harmonic cylinder profile is compared. The results show that the simple harmonic cylinder profile is the ideal cylinder profile of dual working vane compressor
