摘要
随着我国铁路运输的发展,不同类型线路的运营列车在轴重、速度、运输密度等方面都有较大差异,单一列车荷载图式难以反映新形势下的铁路运输状态。本文回顾了我国铁路列车荷载图式的研究和发展情况,介绍了各种类型荷载图式的适用范围和应用中需注意的问题,并提出列车竖向动力作用、列车纵向作用力等需要进一步研究的问题。
With the development of railway transportation in China,there are great differences in axle load,speed transport density of the trains on different type of lines,which means single train load pattern cannot correctly reflect the railway transport in such new situation.The research and development history of China railway train load pattern was reviewed in this paper,applicable range of various load pattern and problems that need to be paid attention to in application were introduced,and some further research issues including train vertical dynamic action,train longitudinal force and etc.were proposed.
