Stable Periodic Response of One-Way Clutches in a Two-Pulley Belt-Drive Model

摘要

The present paper investigates the stable periodic response of a two-pulley belt drive model with a one-way clutch.A dynamic model is developed to couple the rotation of the crankshaft,the accessory pulley and the accessory shaft,and the transverse vibration of the moving belt.The derived piece-wise discrete-continuum nonlinear equations couples integro-partial-differential equations with ordinary differential equations.Applying the 2-term Galerkin truncation method to the two integro-partial-differential equations,a set of nonlinear ordinary differential equations is obtained.The effects of one-way clutch are determined by comparing the stable response curve of the belt drive model with and without one-way clutch.Numerical results demonstrate that one-way clutch not only reduces the amplitude of the angular vibration,but also arouses softening nonlinearities of the moving belt disappears.
