【Abstract】 The work principle of eddy current retarder is presented briefly and the 2D finite element model for the blades on the rotor of HQ6191HS eddy current retarder is established. The boundary conditions are defined and the flow field is numerically analyzed and the distribution of pressure and velocity between blades are shown. The results can be used to improve the design of blade structure, reduce the temperature rise on the rotor and enhance the brake stability of eddy current retarder.更多还原
