| Abstract: | An electrorheological moment amplifier is developed and its work principle and structure characteristics are explained. Then, we research the effects of structural parameters on performance of mechanism and present optimization design methods and control methods. With a view of enhancing the amplification coefficient or increasing the speed of dynamic response, the expectation values of objectives and the weight are obtained and the amplifier with good performance could be designed. In this paper, the parabolic relation between moment amplified and electric field is decided by experimental fit method. And step and pulse electric field signals are used to study the dynamical properties of the device. As the result of experiments, it is confirmed that the electrorheological moment amplifier has good dynamic performance through optimization design methods. |
