Dynamic magnetic circuit analysis of electromagnetic vibration absorber based on corner reluctance
Abstract
The accuracy of air-gap reluctance modeling is vital for electromagnetic vibration absorbers (EVAs). Overcoming the limitations of traditional static models, this study introduces a dynamic magnetic circuit model for a marine EVA that accounts for mover displacement. The model reveals the dominant role of external-corner reluctance, guiding a structural optimization of the magnet configuration, pole shoes, and coil. Experiments validate the design, demonstrating a maximum force output of 838.5 N and vibration suppression of 29–52% under multi-frequency excitation. Both theoretical and finite element models show low errors (below 3.64%), confirming the method’s effectiveness and providing a reliable design framework for high-performance marine vibration control.
