Research on Magnetic-Vibration Combination Treatment Based on Multifield Coupled Finite Element Analysis

Abstract

Abstract In this paper, the three-dimensional simulation modeling of the magnetic-vibration combination residual stress reduction device was established based on the multifield coupled finite element analysis, and the residual stress reduction method of magnetic-vibration combination treatment was researched. The placement mode of the electromagnetic device and the factors affecting the effect of the magnetic-vibration combination reduction were comprehensively studied. The results showed that when the electromagnetic device was placed vertically, it was more beneficial to reduce the residual stress. The electromagnetic frequency was the maximal factor to affect the magnetic-vibration combination, and the factors that followed were voltage, material performance, exciting force, and exciting frequency. The greater the electrical conductivity of the material was, the lower the magnetic induction intensity was. The thicker the steel plate was, the easier it was to magnetize, but it was not conducive to vibration, and there was an optimal thickness under a certain set of parameters. Applying tension to the steel plate was beneficial to increase magnetization to reduce stress, and the aforementioned results of the simulation were consistent with the experimental results. The simulation study in this paper provided theoretical support for the process parameter setting of magnetic-vibration combination treatment to reduce residual stress.
