Eddy Current Retarder Performance Test Systems

Fast speed, more security, less the pollution of the environment and comfort are the aims of the vehicle of the future. Donkey brakes fixed on the vehicle will be indispensably standard equip, the eddy current retarder is one of the donkey brakes, it has more predominance than others and must be abroad used in the future marked. At present, the produce of the eddy current retardet in china has just began, and has difference in quality than abroad, much work must be done to improve the quality. The domestic manufacture of the eddy current retarder starves for a testing system which can test its performance.So, this paper designed a test system who can inspect the eddy current retarder's performance. A series of flywheels are designed which can randomly combine and simulate the running state of the automobiles whose approximately quality range from2000 to 32000(kg), its simulation range is very widely, almost including from camion to motor coach. The testing system can evaluate the eddy current retarder's performance at different vehicles, so it expand application range and heighten testing efficiency, and supply a gap in he eddy current retarder's performance testing of china.The connection of car speed, excitation current, and rotor temperature and brake torsion can be evaluated on this test-bed. Besides, it can give a all-ground evaluate to the eddy current retarder's performance. So, the testing system supplies effective data assist to the eddy current retarder's improving.
