隨著運輸科技的進步,高速鐵路建設在世界各地越來越普遍,為大眾帶來了高效能的運輸系統,但其連帶產生的振動與噪音的問題也逐漸顯現,由於列車行進所引發的地表振動牽涉到車體下方結構支撐系統之形式與設計、基礎土壤的性質與軟硬程度…等等,是相當複雜之問題。
本文研究著重於列車行經路堤路段時所引起地表振動反應,採用台灣高鐵為模型,利用三維有限元素程式予以模擬地表振動行為,並與現地實驗量測結果一同分析評估;研究結果顯示,台灣高鐵行經路堤段之振動反應特徵為低頻振動較小、高頻振動較大,低頻振動位於3與10 Hz左右有較明顯之振動反應,這是由列車載重主要頻率所造成(f=NV/L),另外,程式模擬結果指出,軌道不平整對於路堤結構所造成之振動影響大於高架橋結構,因此,路堤路段最好盡量降低軌道不平整度,以減低行車振動,而且軌道不平整會影響路堤結構的列車載重主要頻率之特徵。
此外,本文也針對台北捷運中和線列車行駛引致振動與噪音進行現地實驗量測,並利用鋼軌與車輪有限元素模型進行接觸動力分析,探討噪音與振動兩者間之相互關係;研究結果顯示,鋼軌與車輪互制之振動均集中在100Hz至1200Hz之間,相信此高頻振動應是噪音主要的來源。
With highly development of the modern traffic, the constructions of high speed rails are more and more widespread through the world. The high speed rails not only bring a convenient, safe, and swift transit system for people, but also produce some annoyances to people, such as ground vibration and noise. The ground vibration caused by moving trains is concerned with the structural supporting system and the properties of soils, which is a complex problem.
This study primarily focuses on the ground vibration due to the train moving on the embankment, and the train model is set to the THSR (Taiwan High Speed Rail). First, this study uses the three dimensional finite element model to simulate the ground vibration and compares with the field experimental results. The result of this study indicates that the characteristics of vibration due to trains moving on the embankment are smaller at low-frequency, and larger at high-frequency. The low-frequency vibration has two peaks at 3 and 10 Hz due to the trainload dominant frequencies of f=NV/L. From the finite element analysis, the influence of rail irregularity is very significant on the vibration response of trains moving on the embankments. Therefore, the best way to reduce the ground vibration is to diminish the rail irregularity. Besides, the rail irregularity will affect the characteristics of the trainload dominant frequencies when trains move on the embankments but very seldom when trains move on the bridges.
Thereafter, this study also investigates the ground vibrations and noise in the Zhonghe Line of Taipei metropolitan rapid transit systems and utilizing the finite element modes of wheels and tracks to proceed the dynamic analysis and probing into the relationship between vibration and noise. The result of this study shows that the high-frequency vibration between 100 Hz to 1200 Hz is primarily the source of noise.
