The Principle and Experimental Study of MR Fluids Stepless Speed Transmission

摘要

Magnetorheological(MR) fluids stepless speed transmission (SST), as a new class MR fluids device is reported rarely. In this paper, two typical structures of MR fluids SST are introduced in detail. In the light of Bi-Viscosity model of MR fluids, the principle of MR fluids SST is discussed, and the calculating model of moment and output rotation speed are established. At last, by experiment on the self-fabricated barrel mode MR fluids SST, the relation of moment and the out magnetic field is studied.
