| Abstract Scope |
Recently, A passive damping technique with viscoelastic material was selected to attenuate structural vibration. The carbonyl iron particles (CIPs) based on MR-elastomer are considered a new group of damping material, which magnetic field change the dynamic flexural rigidity by changing the shear modulus. Therefore, this report aimed to investigate MR-elastomer's viscoelastic properties composed of CIPs contents by 10% volume fraction with various particle chain structures. The experimental testing is evaluated by oscillatory shear excitation as a frequency function and magnetic field strength. The results present that a magnetic field's particle chain structure and strength can enhance the viscoelastic properties. The viscoelastic damping, which means the materials respond to dissipated energy, was induced by magnetic field strength. Moreover, the 45°orientation structure exhibits the most dissipated energies under magnetic field application. The experimental results are very beneficial for designing and considering adaptive vibration control with improving damping characteristics by magnetic field densities. |
