The Magnetic Field

In this study, a testing rig in squeeze was designed and developed with the ability to conduct various tests especially for quasi-static squeezing at different values of magnetic field strength. Finite Element Method Magnetics (FEMM) was utilized to simulate the magnetic field distribution and magnetic flux lines generation from electromagnetic coil to the testing rig. Tests were conducted with two types of MR fluid. MRF-132DG was used to obtain the behaviour of MR fluid, while synthesized epoxy-based MR fluid was used for investigating the magnetic field distribution with regards to particle chains arrangement. Simulation results of the rig design showed that the magnetic flux density was well distributed across the tested materials. Magnetic flux lines were aligned with force direction to perform squeeze tests. Preliminary experimental results showed that stress-strain pattern of MR fluids were in agreement with previous results. The epoxy-based MR samples produced excellent metallographic samples for carbonyl iron particles distributions and particle chain structures investigation.

Magnetic Flux Lines

A magnetorheological fluid consists of a suspension of microscopic magnetizable particles in a non-magnetic carrier medium. In the absence of a magnetic field, the fluid behaves in a roughly Newtonian manner. When a magnetic field is produced in the same space, the microscopic particles suspended in the fluid become oriented and form chains along the magnetic flux lines, changing the fluid’s rheology. The orientation of these particle chains is crucial to producing the Bingham plastic behavior necessary for high strength-to-weight ratio magnetorheological dampers and actuators. This project uses COMSOL Multiphysics finite element software to examine the magnetic flux lines, field intensity, and non-Newtonian fluid flow within a magnetorheological damper. Several established and novel damper configurations are examined and modified to improve performance while minimizing power draw of the electromagnet.
