我国铁路运输中存在着严重的运量与运能的矛盾。近年来虽不断以牵引动力的内燃化、电气化;采用新型电力、内燃机车、长大组合列车等措施提高运输能力,但是不少区段反映轮轨磨耗急剧增长。为此铁道部科技局于1987年下达了“重载运输条件下轮轨磨耗加剧原因的调查与分析”研究课题。铁道科学研究院铁建所与机辆所联合组成了研究专题组承
China’s railway transport there is a serious contradiction between capacity and transport capacity. In recent years, although it has continued to use internal combustion and electrification of traction power, it has also adopted measures such as new electric power, diesel locomotives, and long-distance combined trains to improve its transportation capacity. However, quite a few sections reflect a sharp increase in wheel-rail abrasion. To this end Ministry of Railways Science and Technology Bureau issued in 1987 “under the conditions of heavy haul wheel wear increased investigation and analysis of” research topics. Railway Institute of Iron and Steel Institute and the joint formation of a research group bearing
