在铁路设计工作中,货车平均长度、总重、静载重、每沿米重量等主要参数,对计算铁路行车量有较大影响,并影响到铁路的设备规模及运输能力。随着我国车辆技术进步,70t级车辆将代替60t级车辆,现行设计参数已不适应铁路的发展,本文对设计年度铁路货车主要技术数据进行了计算,提出了2020年、2030年铁路货车主要技术数据的修订意见,并结合设计实例对参数变化后的影响进行分析。
In the railway design work, the average length, gross weight, dead weight, weight per meter and other main parameters have a great impact on the calculation of railway traffic, and affect the equipment scale and transport capacity of the railway. As China’s vehicle technology advances, 70t-class vehicles will replace the 60t-class vehicles, the current design parameters have not adapted to the development of the railway, the paper designed the main technical data of railway wagons in the design year, put forward the main technologies of railway wagons in 2020 and 2030 Data revision comments, combined with design examples of changes in the parameters of the impact analysis.
