OPTIMIZATION OF ANISOTROPIC MAGNETORHEOLOGICAL ELASTOMER (MRE) MOLD WITH VARIOUS ALIGNMENT ANGLE USING FINITE ELEMENT METHOD
In this study, anisotropic magnetorheological elastomers (MREs) mold design with capability of aligning the filler in several angles (0˚, 45˚, and 90˚) were developed. The mold was equipped with electromagnet coil to generate the magnetic flux. The distribution of magnetic flux density in the mold and inside the chamber was investigated by using finite element magnetic analysis. Magnetic flux density of 0.3 T was considered best value to form good particle alignment in the matrix. Moreover, the mold design was fabricated using same material as in the simulation. The magnetic flux density was taken at casing wall and measured by gauss-meter. The data was compared with simulation results. The differences between experimental and simulation is in the range of 6-40 mT. Since the difference is insignificant, it can be said that the data is valid. Finally, the model can be used for further magnetic flux density prediction inside the chamber. In the simulation, it was found the best value to generate at least 0.3 T inside the chamber for 0˚, 45˚, and 90˚ of current and number of turns for …..Turns of coil are …A, ….A, &…..A Respectively.
