The results of centrifugal-rotary processing simulation of parts in granular media are presented. Model of the
process at the microlevel — the movement of single particle of the medium and at the macrolevel — at the level
of complex toroidal-screw motion of the medium in the working chamber is considered. Dependences used for
simulation and determination of quantitative regularities are given.
The results of studies of the method of vibration hardening and finishing processing with high vibration amplitudes are presented. Theoretical models of such processing with classical (traditional) amplitudes are presented, which allow evaluating the surface roughness and depth of the hardened layer. Correction factors are proposed that take into account the effect of high amplitudes on the parameters of the treated surface. Based on the results of experimental studies with high amplitudes, the values of the parameters of the treated surface are determined. The dependence of the steady-state roughness of the surface and the depth of the hardened layer on the value of high vibration amplitudes is established.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
