Abstract

The noise pollution produced by the scraper conveyor affects the working environment seriously. Based on a certain type of the scraper conveyor transmission system as a research object, using the finite element analysis software ANSYS for modal analysis, the results suggested that the natural frequencies of scraper and chute were the same in the 15th order. This indicated that the resonance of scraper and chute in the 15th order was the main cause of vibration noise. According to the above analysis results, an improvement scheme was put forward and then a modal analysis was done to verify its validity. Results indicated that the dynamic rigidity of chute was improved as well as the order of resonance, and the strain values of chute were decreased. The vibration noise would be reduced obviously. In the design process of mechanical equipment, this method for vibration noise test of mutual coupling components could provide an efficient method to reduce vibration noise.
