| Summary: | Utilisation of electromagnet is still expanding to limitless application. The project begun with generating conceptual design for rotor bearing support to include the application of magnetorheological elastomer. Autodesk Inventor was used to construct 3D modelling for the design and conduct static analysis to verify the design before construct the prototype. For this project electromagnet is used to control the properties of magnetorheological elastomer as rotor bearing support system. Initial design of the electromagnet is expected to generate 1 T of magnetic field in order to fulfil the requirement maximum magnetic flux density can be applied to magnetorheological elastomer. The important properties to fabricate an electromagnet have been identified which are the core material, number of coils turns and currents. Strength of electromagnet can be adjusted using the three variables to generate required magnetic field even though with limited clearance of rotor bearing support. From the experiment 0.2 T of magnetic field is recorded from an electromagnet that fabricated using 6 mm core diameter of mild steel, four coils turn and 1A supplied current. Furthermore, the relation between Young modulus properties of magnetorheological elastomer with applied magnetics flux has been studied. Two different specimen magnetorheological elastomer were used which are 5% CIP and 10% CIP. From the simulation it was found that 5% Young modulus increment of MRE with 5% CIP and 10% CIP reached saturation line 0f 0.2 MPa and 0.38MPa when the magnetic flux density reaches 1 T and 1.3 T respectively. |
