Abstract
Recently, a considerable amount of research has been conducted on MRF-based clutches or actuators due to the significant role such device plays in torque coupling and control applications. It is desired to find an accurate yet quick dynamic analytical model to design the electrical circuit of MR clutch. The previous researches on the dynamic response of MR devices have focused on the magnetic response, while less on the current response, mostly on experimental test aspects. Aim at this issue, considering the combination of driving electronics and excitation coil, this study proposes the analytical model from command voltage to excitation current for electrical circuit of MR clutch for the first time. The analytical model develops first principle and is capable of accounting for driving electronics topology and coil configuration. The feasibility of the model was verified by experimental results. Moreover, the model has been implemented to investigate the effect of specific parameters on the electrical circuit dynamic of MR device. As mentioned above, the proposed analytical model provides comprehensive details for optimal design and improvement of circuit performance of MR devices.
