铁路货车主要技术参数设计取值分析

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．

Analysis of the Main Technical Parameter Design Values of Railway Freight Cars

In railway design, the main parameters, including average length, gross weight , static load weight, weight per extended meter, etc. of a freight car , have significant impact on the calculation of the train operation amount, and affect the equipment scale and transport capacity. With the development of the vehicle technology of China, 60 t type vehicle will be replaced by 70 t type vehicle. The current design parameters can not adapt to the development of the railway, so, the main technical data of a freight car in the design years were calculated in this paper. Some revision proposals about the main technical data of the freight cars in 2020 and 2030 were proposed. Furthermore, the influence of parameter variation was analyzed with a design example.
