摘要:本文對某120km/h速度等級的四編組地鐵車輛進行氣密性仿真計算,模擬列車在隧道中運行的車內(nèi)外空氣壓力波動,獲取車體外部和車輛客室內(nèi)部空氣壓力變化情況,結合行業(yè)內(nèi)關于空氣壓力波動舒適度標準,指導車輛各主要部件進行氣密性設計,以滿足整車氣密性設計的要求。

Abstract:This paper simulates the airtightness of a four-group metro with a speed of 120km/h, simulates the pressure fluctuations inside and outside the car when the train runs in the tunnel, to get the air pressure fluctuation Inside and outside the car,integrate standards of aerodynamics about comfortableness in the industry,guides the design of the main components of the vehicle to meet the requirements of the air-tight design of the entire vehicle.
Keyword:metro;airtightness;standards of aerodynamics about comfortableness
隨著城市軌道交通行業(yè)的發(fā)展,越來越多的城市開始建設時速120km/h的地鐵快線,由于車輛速度的提升,車輛客室內(nèi)部的壓力波動幅度也相應增加,直接影響司乘人員乘坐舒適性,因此快速地鐵車輛氣密性設計越來越受重視。(剩余1720字)
