Simulation Research on Braking Torque of Eddy Current Retarder

Research on influence factor of braking torque of one kind of eddy current retarder under existing magnetic yoke effect. One hundred ninety-six simulations were carried out which seven air gap parameters, four coil parameters, seven current parameters were taken for simulating by using Maxwell software according to physical structure parameter of eddy current retarder under existing magnetic yoke effect. Effect relationships that current, air gap and coil number of windings to braking torque were obtained through regression analysis to data of having been obtained by using SPSS software, providing concise and reliable analysis and computational method for analyzing retarderpsilas structure and developing new product.
