For the poor stability and easy to wear belts in the process of belt drive

in consideration of the belt material stiffness and damping conditions

by using of numerical methods

the belt drive system dynamics characteristic are studied.The analysis results show that a certain angular speed loss due to the belt creeping over the pulley surface

the contact force of belt and pulley display a decreasing trend in considering friction factors

with the increase of friction factor

the contact force increase

the contact force under different friction factor with the increase of contact angle shows a trend of twin peaks

at different friction factor

the peak contact force occurs at different location.
