本文介绍了曲爪型真空泵转子的典型型线以及优化型线的构建方法，并由此得到了9种不同的爪式型线。为了找出9种型线中的最佳性能曲线，分别对这9种不同的爪型转子进行工作过程中流场的数值模拟以及转子的受力分析。在数值模拟中，爪型转子工作压力比随着爪尖半径的增加而减小。在应力分析中，随着爪尖半径的增加，转子所受的最大应力减小，其力学性能提高。因此，综合其工作性能和力学性能考虑，爪式真空泵最好选择相对爪尖半径为0.114~0.143的爪型转子。

This paper introduced the building method of typical profile and optimal profile of curved claw type vacuum pump rotor , and obtained 9 different claw type profiles . In order to find out the best performance curves of the 9 profiles , the flow field of working process was numerically simulated , and the stress was analyzed respectively . In numerical simulation , the work pressure ratio of claw type rotor decreased with the increase of radius of claw point . In stress analysis , the maximum stress of rotor decreased with the increase of radius of claw point , and the mechanical properties was improved . Therefore , considering the working performance and mechanical performance,the claw type vacuum pump rotor had better choose relative radius of 0.114~0 . 143 of claw point .
