跨座式单轨应用于市域轨道交通的展望

Prospect of Straddle Monorail Applied in Suburban Rail Transit

跨座式单轨具有投资省、地形适应能力强、环境适应性好、运能适中的特点,可作为我国一线城市轨道交通的补充和二、三线城市轨道交通的骨干制式。然而,受限于传统跨座式单轨80 km/h的速度等级,其在市域轨道交通领域的应用尚不广泛。为进一步发挥跨座式单轨制式的优势,拓展其应用范围,部分单位已经着手研发运营速度100~120 km/h的跨座式单轨车辆。以宜昌市轨道交通2号线为例,对市域轨道交通的制式需求和新型跨座式单轨车辆的技术特征进行对照分析,认为跨座式单轨制式适用于中等运量市域轨道交通,并对其应用前景进行探讨和展望。

Straddle monorail has advantages including low investment,strong terrain adaptability,good environmental adaptability and moderate transportation capacity.It can be used as the supplement of the firsttier urban rail transit and the backbone system of the second or third tier urban rail transit in China.However,limited by the speed level of 80 km/h of traditional straddle monorail vehicles,its application in the field of suburban rail transit is not yet widespread.In order to further utilize the advantages of the straddle monorail system and expand its application range,some companies began to develop straddle monorail vehicles with operating speed of 100~120 km/h.Taking Yichang Rail Transit Line 2 as an example,this paper compared and analyzed the system requirements of suburban rail transit and the technical characteristics of new straddle monorail vehicles.It is proposed that the straddle type monorail system is suitable for medium volume suburban rail transit,and its application prospect is discussed and prospected.
