Dynamic magnetic circuit analysis of electromagnetic vibration absorber based on corner reluctance.
Article in Scientific reports, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

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.
