Static modeling of grinding wheel

In this study, in order to clarify dynamic phenomena of grains in the contact area with workpiece, a dynamic model of wheel is proposed and an experimental evaluation of this model for applications to dynamic analysis is carried out. As the first step of this study, a static wheel model is proposed in which rigid spherical grain particles are suspended by simple bonds having static stiffness k. In this study, elastic deformation of wheel is evaluated by FEM and by three points bending test. As the results of these considerations, it is confirmed that the wheel model proposed in this study can be used to the static analysis on elastic deformations in contact area with workpiece
