Title Title Title Title The Parametric Design o f Tooth Profile f or High Harmonic Drivea nd Dynamic SimulationAbstract Abstract Abstract AbstractThis paper focused on the parametric design of tooth profile of a flexspline for aharmonic drive and harmonic drive device design. Against the shortcomings of involutetooth profile of harmonic drive, such as low carrying capacity, poor quality of themeshing and weak bending fatigue strength, we designed a new circular arc - straightline - circular arc tooth profile for harmonic drive mechanism, which can effectivelyovercome the above shortcomings. For the study, we first designed the benchmarktooth profile of gear - hobbing cutting tools, which machining the tooth profile of aflexspline .And then used MATLAB to design a GUI program to realize the parametricdesign of the tooth profile of a flexspline .This program can achieve functions such asgenerating machining simulation of tooth profile of a flexspline , getting theoreticaltooth profile of a flexspline based on theoretical calculations of the normal method oftooth profile, comparative analysis of machining tooth profile and theoretical toothprofile ,when we input parameters of the flexspline. Finally, Using of ABQAUSsoftware of harmonic drive bearing characteristics are analyzed, and the tooth profileand involute tooth profile of node stress, strain and torsion Angle and so on in the samesituation has carried on the contrast analysis . P rove d that compared with involuteprofile, the bearing capacity is more big, soft wheel deformation and tooth stress aresmaller. Research papers of tooth profile and laid the foundation for engineeringapplications for further in-depth study .
