基于模态分析的矿山防尘装置传动轴稳定性研究
|
Abstract:
近几年来，随着生态发展的需要，矿山防尘装置的研究工作正在逐步开展，而传动轴作为矿山防尘装置中的关键部件，对其振动特性的研究有着重要意义。本文利用SolidWorks对防尘装置进行三维建模，提取传动轴作为研究对象，再将模型导入ANSYS Workbench中，运用约束模态分析求解其前6阶模态，结果显示，传动轴前6阶的固有频率散布在473.53~2239.4 Hz之间，振型以弯曲变形为主。通过模态分析反映出传动轴的动态特性，结合实际工况分析传动轴工作时的稳定性，为抑制矿山防尘装置整体振动和传动轴变形提供了理论依据。
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 analyzed 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.
