Abstract

Abstract : Giant electrorheological fluid (GERF) is a kind of intelligent material whose shear yield stress can be adjust continuously by changing the applied electric field and has potential to be used in clutches and multi-axis transmission systems. According to the rheological characteristics of GERF, an actuator based on parallel plate electrodes is designed and a soft transmission mode is proposed to realize a tuneable torque output capacity. The driving principle of the soft transmission, the rheological model of GERF, the design scheme of the actuator is discussed, and verified with experiments. The experimental results show the relationship between the output torque and electric field intensity, centre distance and electric field type, and suggest the feasibility of applying this driving principle to multi-axis drive system in the future.
