Serpentine belt has been widely used for automotive engine accessory drive belt. The belt sometimes causes abnormal noise problem by its slip and/or span vibration. Our formerly developed belt motion analysis program cannot predict belt span transverse vibration. Then we developed new belt motion analysis simulation using commercial Multi-Body Dynamics code. Calculated results agreed with experimental measured one well. It made mechanism of belt span transverse vibration clear. By using this analysis in early design stage, it is possible to prevent accessory belt problems and to optimize belt system layout.
