Numerical and Experimental Investigation on Braking Characteristics of an Electro-Rheological (ER) Micro Brake

抄録

Micromouse contest is a kind of world popular competition for micro-mobile robots. Due to excellent mechanical performance, the electro-rheological (ER) brake has a great potential to realize smooth and rapid turning of the micromouse in the maze. A small-scale disc type ER brake is proposed and developed in this paper. Aiming to predict the performance of the ER brake, the mathematical model of the braking torque is established based on the constitutive model of one particle type ER fluid (ERF). The static and dynamic braking characteristics of the ER brake under different applied voltages are simulated and tested. The braking effect is verified by the good agreement between the simulated and tested results.
