铁路运输部门的特点之一,就是动力主要消耗在克服摩擦阻力上,维修费用的主要部分用于修理摩擦所造成的磨损部件。因此,在铁路系统开展摩擦学方面的研究,对于节约能源和促进铁路运输经济的发展具有很大意义。英国铁路运输应用摩擦学知识,每年至少可节约2700万英磅。我国铁路业务范围比英国广,其营业里程为英国2.5倍,节约数字更大。
One of the characteristics of the rail transport sector is that power is mainly consumed in overcoming the frictional resistance, and the major part of the maintenance costs is used to repair the worn parts caused by friction. Therefore, the research on tribology in the railway system is of great significance for saving energy and promoting the economic development of railway transportation. Tribological knowledge of British rail transport can save at least 27 million pounds a year. Our railway business is wider than that of the United Kingdom and its operating mileage is 2.5 times that of the United Kingdom, saving even more.
