中文摘要 | 當列車以高速進入隧道時,會產生明顯的壓力變化,而此壓力變化會影響乘客的舒 適度。因此有必要針對隧道的空氣動力進行分析,以設法降低壓力變化量。本文係針對 台北捷運系統環狀線出土段,利用三維數值模擬,分析不同線性喇叭型緩衝結構角度之 壓力變化情況。經由模擬分析,求得最小需求及最佳的線性喇叭型緩衝結構角度,並針 對設計採用之線性喇叭型緩衝結構角度進行詳細評估。 |
英文摘要 | An obvious pressure change is generated when a train enters a tunnel at high speed, causing an impact on passenger comfort. Thus, an analysis and assessment of aerodynamics is a necessity in order to reduce the pressure change. This paper aims to analyze the pressure change from a variety of angles of linear horn hoods on the Taipei MRT Circular line's daylighting section using 3-dimensional numerical simulations. Through simulation analysis, the minimum and the optimal angles of the linear horn hoods have been gained for design use. In addition, this paper examines the design angle of the linear horn hood in this project. |
