철도차량용 와전류 브레이크 축소모델 제작 및 실험

초록

The rail cars are generated the braking torque using the air braking system with regenerative braking. Air braking system, brake friction with the air, results in a change in the braking torque because of high maintenance cost, abrasion, noise and dust. A scale model that corresponds to the size of 1/50 was manufactured, conducted an experiment to verify the Drum-type eddy current brake electromagnet to complete the problems of the air brake system on a railway vehicle application. Designed and manufactured eddy current scaled model were compared to the braking torque changes in the RPM of the drum and analysis the changes in the braking torque due to the temperature rise.
