The Noise Control and Research of Vibration Slot in Vibrating Conveyor

Abstract

Vibration slot, which is connected by the framework welded by the angle and the u-shaped slot formed by the stainless steel plate bending with fasteners, is an important part of the vibrating conveyor. The major function of vibration slot is carrying and conveying material. Due to vibration slot owning the thin plate structure and the flat large feature of surface, it is the primary noise source of vibrating conveyor. Therefore, it is very important to research and control the surface radiation noise of the vibration slot for reducing the noise of vibrating conveyor. This paper, through combining the finite element and the boundary element, researches noise radiation of vibration slot and understands the main noise source of vibration slot and radiation condition. The natural frequency of vibration slot, the vibratory response of vibration slot and the noise radiation of vibration slot are researched by inputting different structure parameters. Through analysis and comparison, some regularity conclusions that will provide a basis for the noise reduction of vibration slot are summarized .
