Abstract: This paper presents the design of actuator using magnetostrictive material under zero prestress conditions for direct current input, which is being developed to move friction pads of a disc brake for braking action. Comparison of analytical, experiment and Maxwell simulation of coils in free air is being carried out to predict the magnetic field generated by them and magneto motive force reaching the measuring end of magnetostrictive material. Experiments are being conducted to verify the performance of magnetostrictive actuator for dc input under zero-preload conditions. A set of magnetization curves are being predicted using Jiles-Atherton model in the context of control applications that require an accurate characterization of the relation between input applied magnetic field and strain output by the actuator. Further the validation of Jiles-Atherton model results is being done with the results obtained from experiments. � (2013) Trans Tech Publications, Switzerland.
