Study on the Stability of Mine Dustproof Device Transmission Shaft Based on Modal Analysis

Abstract

In recent years, with the needs of ecological development, the research work of mine dust prevention device is gradually carried out, and the transmission shaft as a key component of mine dust prevention device, has important significance to the research of its vibration characteristics. In this paper, SolidWorks was used to conduct 3D modeling of dust prevention device, and the drive shaft was extracted as the research object. Then the model was imported into ANSYS Workbench, and the constrained modal analysis was used to solve the first 6 order modes. The results showed that the natural frequency of the first 6 order of the drive shaft was distributed between 473.53 and 2239.4 Hz. The vibration mode is mainly bending deformation. The dynamic characteristics of the drive shaft are reflected through the modal analysis, and the stability of the drive shaft is ana-lyzed in combination with the actual working conditions, which provides a theoretical basis for suppressing the overall vibration of the mine dustproof device and the deformation of the drive shaft.
