Simulation of a pre-structure device for fountain-like magnetorheological elastomer via Finite Element Magnetic Method (FEMM)

Abstract

The ability of a pre-structure device for curing the fountain-like alignment of CIPs in a magnetorheological elastomer (MRE) is simulated in this study. In order to generate the fountain-like magnetic flux in the device, the device was equipped with an electromagnet coil and a cylindrical permanent magnet to pick-up the pass magnetic flux trough the MRE mould. While the electromagnetic coil is utilised to control the generated magnetic flux density in the device via manipulating induced currents for different magnetic fields. The analysis then was conducted by using Finite Element Magnetic Method (FEMM) software to determine the magnetic flux density in the device as well as the fountain-like shape of magnetic flux lines that flew in the MRE mould. In the simulation, the primary factor in determining the strength of the magnetic field across the mould is the change in current. The simulation has found that the current required to generate around 0.24T is about 1A comprise of electromagnetic coil and permanent magnet.
