Pendulum Surface Plastic Deformation of Cylindrical Blanks

Abstract—The article discusses the features of kinematics regarding working tool a circular sector shape during hardening by pendulum surface plastic deformation (PSPD), which is carried out in two successive process steps – rolling and sliding contact zone deforming element blank. Forecasting possibility its application for finishing processing cylindrical parts such as shafts axles presented; kinematic parameters SPD rectangular coordinate system are described. Based on analysis components motion types (rotational, translational, oscillatory) blank functions trajectory length, magnitude resulting velocity acceleration were determined, make it possible to control technological modes process. Reliability confirmed results simulation ANSYS 19.1 software program. The dynamic modeling showed that under same conditions with stationary position opposite rotation intensity temporal stresses increases 10 17%, respectively, compared scheme. With SPD, sharply reaches maximum value (485 MPa), distribution uniform comparison other methods. In addition, regularity over cylinder depth shown where clear case h has higher (by 1.5–2.3 times). Under conditions, highest hardened zones obtained (h = 2.8 mm), leads changes physical, mechanical operational properties deeper layer.
