Abstract
This article presents an experimental and theoretical study of vibration analysis of a magneto-rheological fluid-based sandwich plate. Two sandwich plates consisting of polyethylene terephthalate face layers were fabricated with two different magneto-rheological fluids (MRF-132DG and MRF-122EG) as the core layer and silicon rubber spacer as the sealant. The dynamic responses of the cantilever sandwich plate were experimentally characterized. A finite element model based on the Classical Plate Theory was formulated to obtain governing equations of motion of the multi-layer magneto-rheological plate. The complex shear modulus of each magneto-rheological fluid in the pre-yield region was described by a phenomenological model as a function of the magnetic flux density and excitation frequency. The results clearly showed enhanced vibration suppression properties of the magneto-rheological sandwich plate over a broad frequency range through variations in both the stiffness and damping.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
