Spindle Vibration Characteristics of Form Grinding Machine on ANSYS

Spindle is an important part of grinding machine,the dynamic characteristics of the spindle has a great impact on gear grinding precision and production efficiency.Taking the grinding machine spindle system as the research object,this paper established a finite element model,carried out the modal analysis by finite element software ANSYS,and got the natural frequencies of the spindle system and the maximum polarization.The influences of different span and different spindle material on the dynamic characteristics of the spindle were analyzed,its inherent law was summarized through a comparative analysis of the data,in order to provide meaningful reference for the further study on grinding machine spindle vibration characteristics.
