ADVANCE IN ANALYSIS OF VIBRATIONS OF SERPENTINE BELT DRIVE SYSTEMS

Advance in vibration analysis of serpentine belt drive systems with a dynamic tensioner in automotive engines is reviewed. Linear and nonlinear rotational vibration analysis and slip prediction, based on the mechanical and mathematical models, by numerical approaches, complex modal analysis methods and incremental harmonic balance method, are surveyed. Analysis of linear and nonlinear coupled vibration of rotational and transverse motions based on the mechanical and mathematical models, by numerical approaches, Holler's method, modal analysis methods and direct multiple scales method, are also surveyed. Some problems for further investigations are discussed.
