Abstract：[Objective]In order to improve the meshing performance and design efficiency of harmonic gears,a tooth pro-file optimization method aiming at increasing the meshing conjugate interval was proposed,and the design and analysis software was developed.[Methods]Firstly,based on the basic principle of harmonic gear transmission,the mathematical model of theoret-ical conjugate region and conjugate tooth profile was established,and the tooth profile of the rigid gear was obtained.Then,the genetic algorithm was used to optimize the tooth profile parameters of flexspline,and the assembly state,motion trajectory and meshing backlash of harmonic gear before and after optimization were compared.Finally,the software integrating parameter op-timization and meshing characteristic analysis was developed based on the App Designer module of Matlab software.[Results]The results show that the number of meshing teeth after optimization is increased by 8,an increase of 7%.The tooth profile clearance is reduced by 34%.The meshing interval is increased by 3.8° and 7.4%.The developed software provides an efficient means of design analysis for industrial applications.
