Abstract
本文研究的目的，在於探討高速鐵路列車之輔助煞車系統-渦 電流煞 車的結構分析，並進行數學模式推導和實驗驗證。 由於軌道列車高速化 後，輪與軌間的黏著力會降低，影響到列 車的加速及煞車力，為提供列 車於高速下仍具備足夠的煞車能 力；本文中針對此種與黏著力完全無關 的渦電流煞車器，分別 以數學解析、實驗驗證等方式進行研究，在考量 鐵軌的非線性 磁化特性時，並提出合理的數學模式，進一步用電腦分析 渦電 流煞車系統作用時，對鐵軌所造成的溫升效應。本文並以實驗 來 驗證在列車高速下渦電流煞車的特性，並對渦電流煞車器進 行定煞車力 控制之數值分析與驗證實驗。 The objective of this thesis is to provide an auxiliary braking system, namely eddy current brakes, for the high speed railway vehicles. Due to the reduction of the adhesions between the rail and the wheels are in high speed region, the acceleration and braking forces based on the adhesions are reduced. In order to provide sufficient braking capacity for the high speed vehicles, a thorough analysis based on the Fourier Series for eddy current brakes has been conducted. In the thesis, nonlinear BH magnetic characteristics of the rail have been considered. The results based on the method have been compared and high speed experimentation has been employed for verifying the simulation results. Also, further analysis on the temperature rise on the rail surface has been investigated by numerical simulations. In addition, test results on constant braking force design have been shown in this thesis to illastrate a possible way on controlling the brakes.
