中文摘要

高雄輕軌捷運為台灣第一次引進嵌埋式軌道系統，國內對此種軌道系統的分析、設計與施工經驗尚十分缺乏。為瞭解捷運車輛通過軌道引致結構振動及噪音對周圍環境之影響，本文建立聲學流固耦合分析流程，數值模型包括振動分析模式及聲場分析模式，採用單向耦合數值方法進行振動噪音模擬分析與探討。為瞭解軌道系統數值模擬之準確性，進行高雄輕軌捷運現場振動噪音試驗，量測列車通過時之振動速度與聲壓，並與數值模擬結果進行比較，確定此聲學流固耦合分析流程之可行性。本文所得結果可提供未來嵌埋式軌道系統減少振動與降低噪音之設計參考。
英文摘要

The Kaohsiung light rail transit (LRT) system first introduced embedded rail system in Taiwan. However, domestic engineering consultants are still lacking in experience of analysis, design and construction of embedded rail systems. Noise and vibration of the mass rapid transit system is an important environmental issue in an urban environment. In order to understand the environmental impact of noise due to structural vibrations caused by a train running on the rail system, this paper establishes a numerical analysis procedure to perform a simulation. There are two fundamental parts to the numerical simulation: (1) vibration response due to a moving load and (2) radiation propagation of noise induced by structural vibration. The Kaohsiung LRT is used as a case study. The real embedded rail track system is modeled using ANSYS software with finite element analysis and the dynamic time history of the vibration response of the rail caused by a moving load is obtained. Secondly, the dynamic vibration response of the rail outputted by ANSYS is then imported into the software LMS Virtual.Lab to obtain the external radiation and sound field pressure distribution transferred from the rail to a specific monitoring point, based on the boundary element method. This paper also conducts field measurements of vibration velocity and sound pressure as a train passes. Both the experimental and analytical results for noise at specific points are compared and discussed. The proposed procedure promises to be suitable for practical vibration and noise analyses for rail systems.
