Simulation and experimental validation of the mechanisms underlying the reduction and enhancement effects of Magnetic-Vibration composite treatment

Abstract

Employing the COMSOL finite element software, this research has devised an intricate multi-physics field coupling simulation model focused on scrutinizing the macro-scale magnetic-vibration treatment process. Its aim is to offer a quantitative delineation of the mechanisms underpinning the enhancement effect associated with magnetic-vibration treatment. Through the application of modeling and simulation techniques, this inquiry adeptly replicates the synergistic reduction effect enhancement induced by magnetic-vibration treatment. The simulation findings provide quantitative substantiation of magnetic-vibration treatment's amplified reduction effect, approximating a factor of “1 + 1≈2.78″ when compared with individual treatment methods. Additionally, this investigation delves deeply into the implications of magnetic frequency and vibration frequency, shedding light on the mechanisms driving the augmentation of the residual stress reduction achieved through magnetic-vibration treatment. Notably, when the magnetic frequency aligns with the vibration frequency or becomes an integer multiple thereof, a pronounced enhancement effect is observed. Importantly, the study underscores the association between the efficacy of the magnetic-vibration treatment method and its enhancement effect with the thickness of the material component.
