Finite element modeling method of centrifugal rotary processing

Introduction. In modern production, when performing finishing operations, centrifugal rotary processing in the medium of abrasive plays an important role. High productivity, low costs and extensive technological capabilities are the main advantages of these cleaning and finishing operations. This paper considers the process of abrasive particle - workpiece surface interaction within the framework of the static contact problem of the elasticity theory. Thus, plastic deformation in the contact area comes into account.Materials and Methods. The abrasive particle (corundum) is simulated with a linearly elastic body, whose Young's modulus is significantly larger than that of the work material. The process material (steel) is simulated with an elastoplastic bilinear body using the von Mises yield criterion.Research Results. Finite element modeling of the structures under consideration was performed in the ANSYS CAE package. The process of abrasive particle - workpiece surface interaction was simulated; its stress-strain state was analyzed...
