Abstract

The behaviour of three types of magnetorheological fluids under squeeze mode was investigated. A special device was designed and fabricated to perform these experiments which were carried out on an Instron Multiaxial Testing Machine. The hysteresis loops of the MR fluids were studied for different intensities of magnetic field, frequency, strain amplitude and angular amplitude. The results showed that the damping force and the area of the hysteresis loop of MR fluids increase with the magnetic field (or electric current i) and displacement amplitude (x₀). Changes to the frequency (f) produced different behaviour of the various MR fluids. The peak compressive force was found to increase with the increase in number of cycles (N).
