混凝土材料、高分子材料(橡胶、塑料和涂料)、润滑剂或粘接材料、轨道、车轮、轴承、制动器和接触导线等用材料,以及超导材料之类的新材料等,正在铁道系统中得到应用或者为将来的应用进行着研究。在回顾涉及这些材料和材料技术的研发课题近25a的进展时,除了有关高性能或高经济效益的课题外,还增加了考虑环境因素的课题。有些领域则由于停用有关材料等原因,没有列入计划中的研究。最后,介绍了各研究领域的最新成果。
Materials such as concrete, polymer materials (rubber, plastics and coatings), lubricants or adhesives, rails, wheels, bearings, brakes and contact wires, and new materials like superconducting materials are being used in railroad systems Get applied or research for future applications. In reviewing the progress made in R & D projects involving these materials and materials technologies in the recent 25 years, we have raised the issue of environmental considerations in addition to the issues related to high performance or high economic efficiency. Some areas are not included in the planned studies due to the discontinuation of related materials. Finally, the latest achievements of each research area are introduced.
