Abstract
The dynamic simulation model of synchronous belt meshing transmission is established in dynamics software “RecurDyn” applying the theory of MFBD (Multi-Flexible Body Dynamics), which analyzed the contact force on the working surfaces and stress distribution during the meshing transmission. The Finite Element Analysis Method was used to make the synchronous belt model meshed in Femap and investigated the belt's teeth stress distribution after the model was imported into RecurDyn. A new design of synchronous belt's and pulley's tooth profiles for improving the transmission capacity of the automotive synchronous belt was proposed, in order to discover better materials to increase the fatigue life of the belt by optimization of the geometry of tooth profiles.
