本文之目的是探討列車系統及軌道系統間耦合振動之動態分析。並用此方法研究臺北捷運列車對週遭環境所造成之振動問題,作一系列相關之分析與討論,以期能將臺北捷運列車通過時對週遭環境之影響能夠降到最低。
在車體-軌道耦合系統方面,使用集總參數(Lumped parameter)模型與連續彈性離散點支撐樑模型,配合高階機械系統動態分析軟體,分析臺北捷運系統之耦合振動,並且模擬加入一浮動道床系統後,對於整個捷運系統之影響改善。
在輪軌噪音方面,將其分為軌道與車輪兩部分。分別使用有限元素分析軟體,分析臺北捷運鋼軌(UIC60)以及臺北捷運西門子(SIEMENS)系統列車與川崎(Kawasaki)系統列車於各式不同邊界條件之自由振動頻率與振動模態,再與實際實驗作一相對比較,找出產生噪音之主要機制。
The aim of this thesis is to confer the dynamic analysis of vehicle - track systems. We use the method to find the Taipei Rapid Transit’s vehicle cause a series of problem and discuss it. We hope the influence on the environment reducing when the Taipei Rapid Transit’s vehicle passes through.
In the vehicle-track coupling systems, we use lumped parameter model and continuous elastically beam model with being supported by dispersed point. The high-level mechanical dynamics simulating software undertakes the coupling vibration of the Taipei Rapid Transit System. We also simulate the influence and improvement when adding the floating slab track system to the Taipei Rapid Transit system.
In the wheel-rail’s noise, we separate it into wheel and rail system to discuss. We use the finite element analysis software to undertake the nature frequency and model analysis of Taipei Rapid Transit’s rail (UIC60), Taipei Rapid Transit’s wheels (SIEMENS system and Kawasaki system) with different boundary conditions. We also compare the analyses and the experiment in order to find the place to produce noise.
