Study of Noise of Accessory Belt under Cold Condition 2011-01-0929
This paper presents an experimental study of automotive V-ribbed belt slip noise under cold condition. In this study, a set of experiments was conducted to investigate the properties of the belt noise and friction using a self developed rig. The belt friction under cold condition is found to have higher value than that in room condition. The belt noise under cold condition is found to have much higher squeal frequency than that in room condition. This study is expected to provide accessory drive designers some fundamental understanding of belt startup noise under cold conditions.
