Abstract

The objective of this paper is to explore the dynamic features of vibrations and instability of the front-end accessory drive belt system. A non-linear model of a moving beam with friction coupling on an elastic foundation is developed. The model takes into account a variety of non-linear effects, including the contact stiffness non-linearity, non-linearities associated with the friction, tensioned parametric excitation, as well as the beam geometry non-linearity. Different non-linear properties are examined, and numerical simulations are conducted to investigate the system and to correlate with the experimental results. The major contributors to the dynamic contact instability are illustrated.
