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.
隨著我國鐵路運輸的髮展,不同類型線路的運營列車在軸重、速度、運輸密度等方麵都有較大差異,單一列車荷載圖式難以反映新形勢下的鐵路運輸狀態.本文迴顧瞭我國鐵路列車荷載圖式的研究和髮展情況,介紹瞭各種類型荷載圖式的適用範圍和應用中需註意的問題,併提齣列車豎嚮動力作用、列車縱嚮作用力等需要進一步研究的問題.

W ith 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. w ere proposed.
