Analysis on the Effect of Support Structure Deformation on the Vibration Characteristics of Drive Shaft

摘要

The drive shaft is important part of power transmission system for most mechanical equipment, which has directly influence on not only keeping normal operation crucially in the set course, but also the vibration of equipment. There are several influence essential factors of the vibration characteristic. Support structure deformation is one important factor with incapable avoidance. In worst case, it would lead the heavy damage of equipment. The simplified model of typical drive shaft was the narrow sense concept for this study. This paper used research means including theoretical analysis 、 numerical calculation and experimental verification. Based on the dynamic equations, this paper aims to establish the dynamic model of the drive shaft. The analytical results of the model are compared with the numerical and experimental results to confirm that the model is reliable. The shaft vibration characteristics are studied under structure deformation with different parameters respectively. The analysis of model experiment can guide the design and installation technology of drive shaft .Groundwork is made for further research in shaft vibration problem considering support structure deformation.
