Influence of Temperature on the MR Squeeze-Mode Damper

In the paper the authors present the results of a numerical study involving a magnetorheological (MR) fluid damper operating in squeeze-mode. The study is an attempt to analyze both heat generation and heat dissipation mechanisms within the device. In this numerical experiment an exemplary squeeze-mode device is evaluated for temperature changes resulting from mechanical and electrical inputs, respectively. We solve the resulting model based on the Stefan model, and then couple it with a lumped parameter model of the electromagnetic circuit of the actuator. In the resulting analysis the model is subjected to various types of mechanical and electrical stimuli, respectively. Finally, we present the numerical results for temperature rise and force fading.
