Abstract

Abstract

To verify the accuracy of Hertz contact model in belt grinding, a contact finite element model of abrasive belt grinding is established by using ABAQUS software.The influence of several factors on the contact pressure and the contact parameters are analyzed, namely the thickness ratio, the rubber hardness, the contact pressure and the curvature radius of workpiece.The rationality of the model is proved by contact experiment between the rubber contact wheel and the planar or curved workpiece.The results of analysis and test show that the contact state of abrasive belt grinding is basically in accordance with Hertz contact theory, ignoring the less influential factors.When the cylindrical contact wheel is in contact with the curved workpiece, the contact stress distribution is semi ellipsoidal, which is verified by the finite element analysis and the test results.When the thickness ratio is 20% and the Shore hardness of rubber is 70 HS, the mechanical properties of the rubber contact wheel have the least error with the Hertz contact theory.
