Abstract

This paper is aimed to model behaviour of a magnetorheological (MR) damper under impact loading through polynomial approach. The polynomial model is developed based on curve fitting from experimental results and consists of a three regions namely fluid locking, positive and negative acceleration regions. The experimental results which have been performed using impact test apparatus are evaluated in the form of transmitted force in velocity, displacement, and time domain. The simulation results of the proposed polynomial model are then compared with the experimental results. Results show that the proposed polynomial model closely follow the experimental data in the three regions under study namely fluid locking, positive and negative accelerations.
