Abstract
Almost all the problems of a serpentine belt drive system such as maximum tension, belt slip on the pulley, squeal noise and self-exciting string vibration of the belt are caused by a resonant phenomenon of the belt drive system. In this report, the following items are described on the resonant phenomenon. (1) Eigenvalue analysis that is the method to get the natural frequency, resonant speed and vibration mode of the belt system. (2) Tension mode that can estimate the span of self-exciting belt vibration occurrence, and slip mode that can estimate the pulley of squeal noise occurrence. (3) Some application examples of eigenvalue analysis and methods to avoid or reduce the resonant phenomena.
