Measuring of Noise Character on Cogged Belt Using Order Tracking and Design of Belt Shape

Order Tracking 을 이용한 Cogged belt 소음특성의 측정 및 구조변경 설계

Cogged belts get unpleasant noise when the speed is up and down. This paper investigates optimum condition for reducing a belt noise that is caused by a belt shape and properties of the material. Order tracking is used analyze belt noise. First step, the pitch length exerts an important influence on the order noise. Second step, material of belt is also important for reducing noise level. The experimental results showed the modified form and material of belts to reduce the noise.
