悬挂式单轨交通最小曲线半径及曲线限速研究
|
摘要
研究目的:悬挂式单轨交通目前在我国公共交通领域尚未有运营线路,相关研究资料较少,为适应国内山地城市和旅游城市对悬挂式单轨交通的发展需求,对悬挂式单轨交通技术标准进行研究具有重要意义。本文针对悬挂式单轨交通的特点,对悬挂式单轨交通的最小曲线半径及曲线限速值进行研究,提出各种运行速度下线路最小曲线半径的建议值,以及曲线速度限制值的计算方法,以期为悬挂式单轨交通设计及规范编制提供参考。研究结论:(1)悬挂式单轨交通线路平面曲线半径宜适应列车运行速度要求,当最高运行速度为60 km/h时,悬挂式单轨交通线路最小曲线半径可取200 m;当最高运行速度为50 km/h时,最小曲线半径可取150 m;(2)当不具备设置满足速度要求的曲线半径时,可按V=4.52R~(1/2)计算曲线速度限制值,且不大于列车的最高运行速度;(3)本研究成果对悬挂式单轨交通线路设计标准确定及规范编制具有参考价值。
Research purposes: Suspended monorail transportation currently has no operating routes in China's public transportation field, and there are few relevant research materials. In order to meet the development requirements of suspended monorail transportation in many mountainous cities and tourist cities in China, it has important significance to study the technical standards of suspended monorail transportation. In this paper, based on the characteristics of suspended monorail traffic, the minimum curve radius and curve speed limit of suspended monorail are studied. The recommended values of the minimum curve radius of the line at various operating speeds and the calculation method of the curve speed limit value are proposed in order to provide reference for the design and code compilation of suspended monorail.Research conclusions :(1) The plane curve radius of the suspended monorail traffic line should be adapted to the train running speed requirement. When the maximum running speed is 60 km/h, the minimum curve radius of the suspended monorail traffic line can be 200 m. When the maximum running speed is 50 km/h, the minimum curve radius can be 150 m.(2) When there is no setting to meet the speed requirement curve radius, the curve speed limit value can be calculated according to V = 4. 52 R~(1/2),and is not greater than the maximum running speed of the train.( 3) The research results could provide reference for standard determination and code compilation of suspended monorail line.
