博士 === 國立臺灣科技大學 === 電機工程系 === 105 === The current braking devices of trains have not only braking function but also recycling power function in some trains. The functions to prevent the derailment of rail trains and slip between wheels and rails and to increase the climbing force is still not perfect. In order to improve the above-mentioned functions and increase traffic safety, this dissertation proposes the use of physical properties of magnetic components not to damage the wheels and rails. The electromagnetic components set on the bogie axle. The use of circuit loop drives voltage and current. The front and rear wheels produce magnetic force. This dissertation study attractiveness and beating frequency between steel wheels and rails to reduce the derailment rate and the braking distance. The results of this study show that the braking distance can be shortened and the wheel-rail slippage and coasting can be reduced. Finally, the reduction of the beating frequency between the wheels and rails is verified by the neural network experiment.From the verification, it can be seen that the reduction of the beating frequency is in good agreement with the actual test results. This dissertation can significantly improve traffic safety and reduce personal injury and financial losses.
