Vibration Control of Magnetorheological Nanocomposites Isolator

Abstract:

A novel tunable stiffness and damping vibration isolator based on magnetorheological nanocomposites filled with carbon nanotubes (CNMRE) was proposed. The stiffness and damping is controlled by the current applied to the magnetic excitation coil. Under the combined ON–OFF control law, the proposed vibration isolator shows satisfying isolation effect. The simulation results indicate that, in comparison to MRE isolator with ON–OFF stiffness and damping control, CNMRE isolator with ON–OFF control not only has high stiffness and damping capacity, corrosion resistance, and high failure strength which are demanded in industries, but also significantly suppresses vibration under sinusoid excitation, random excitation, and pulse excitation. The proposed vibration isolator is very simple and easy to be applied in practical system.
