Study on the Vibration of a Sandwich Beam with Smart Composites—MRF


Article Preview

Smart composite material-MRF’s rheological properties such as viscosity and shear modulus can vary when subjected to different magnetic fields. This paper established the vibration model of the smart composite beam featuring MRF. The vibration analysis was finished under different magnetic field strengths using the method of complex stiffness. The experiment was performed to validate the theoretical predicted vibration responses. From both studies, the natural frequencies and loss factors of the MRF beam were shifted to a higher lever when the applied magnetic field increases. From the findings of the analysis, it is observed that MRF presents vibration control capabilities.
