Original Article Development ofa orheological brake with a slotted disc Proc IMechE Part D: J Automobile Engineering 2015, Vol. 229(14) 1907 – 1924 ó IMechE 2015 Reprints and permissions: .nav DOI: pid. 1 and Harish Hirani 2 Chiranjit Sarkar Abstract A conventional disc wears out and the brake pollutes the environment. Brake pad dust is reported to be the largest 1. The particles emanating because of wear of the brake pad pollute the environ- source of environment pollution 2,3,4 . In addition to pollution caused by wear particles, the friction-induced noise between the brake pad and the ment 5. Also, localized heating occurs ina conventional disc brake. To tackle both of these prob- disc is also a major concern lems, conventional disc brakes can be replaced with orheological fluid brakes. orheological fluids are mate- rials having a shear yield stress which isa function of the ic field. On the application ofa ic field, orheological particles e aligned and increase the shear resistance between relatively moving surfaces. The friction between the stator and the rotor increases and fulfils the braking function, which means that orheological fluids can be used as brake friction materials. A orheological brake consists ofa rotating disc or discs immersed ina orheological fluid and enclosed in an ic casing. The torque charac
