Study on the Stress Distribution of Grinding Wheel Based on ANSYS under Multi-operating Modes

This paper estabLishes a finite element model of grinding wheel and the stress analysis is carried out under idLing, normal, and abnormal conditions separately. On idLing condition, the tangential stress is the main failure factors of grinding wheel by the effects of centrifugal force. The stress distribution of grinding wheel on normal conditon is consistent with the abnomal condition´s. When working in the same conditons, the equivalent stress of grinding wheel with side force are far greater than that of grinding wheel witHout side force, and more vulnerable to grinding safety accident. The conclusion in this paper provide a strong basis for the further study of failure mechanism and the structure design optimization of grinding wheel.
