Pre-Stressed Modal Analysis of the Shaft Based on ANSYS Workbench

Article Preview

Abstract:

This paper is based on the research on the drive shaft of the toothpaste tube conveyor, using Solidworks to create the three dimensional model of the frame of the soft tube conveyor and the drive shaft. And natural frequencies and vibration modes of preceding 6 modalities of pre-stress modal analysis are calculated with ANSYS Workbench. By analyzing the natural frequencies of the drive shaft and the resonance range of stepper motors, the reasonable speed range of the stepper motor can be acquired, in order to avoid the resonance between the drive shaft and stepper motor. At the same time, the reasonable installation location of synchronous belt wheels can be attained by analyzing each vibration mode.
