Improvement of part service properties under surface plastic deformation treatment by dynamic methods

https://doi.org/10.12737/10394

Abstract

The process of improving the surface layer quality and service properties of the machine parts in response to the treatment of the surface plastic deformation (SPD) using the dynamic methods is studied. The aim of the work is to improve the efficiency and reliability of the surface layer processing through the use of the adequate theoretical models at the technological design stage. The study results of the effect of the dynamic pressure maintenance methods (PMM) on the part performance properties are analyzed. The dependencies for the determination of the surface roughness and the hardened layer depth are proposed. The flow analysis of the dynamic PMM has shown that despite a large number of the theoretical and experimental studies, the prediction of the residual stresses in the surface layer is quite a challenge. The application of the universal program system ANSYS which is based on the finite element method (FEM) allows to accurately calculate the stress-strain state parameters of the part surface layer after processing. According to the computer simulation results, the residual stress distribution graphs are presented, and the validity of the offered theoretical models is established. The research results can be used to predict the surface layer quality and the part service properties after processing by the dynamic PMM at the technological design stage.
