摘要
阐述了国内外铁路运输事业的发展历史与现状,指出当下高速铁路建设中存在的技术难题。为了解决轮轨之间的关键问题,研究了疲劳损伤产生和发展的机理和影响因素,结合轮轨接触疲劳的失效形式和磨损的特点,进一步提出预防和减缓疲劳损伤的具体措施。同时指出铁路事业的发展亟需解决节能效率和降低能源消耗等一系列问题,对高速铁路的建设和发展具有实际的意义和价值。
This paper expounds the developing history and current situation of railway transportation in China and abroad, pointed out the problems present in high speed railway construction. In order to solve the key problem between wheel and rail , the factors of the emergence and development of fatigue damage mechanism and influence , combined with the wheel-rail contact failure forms and wear characteristics of fatigue, further put forward concrete measures to prevent and relieve the fatigue damage. At the same time, points out that the development of railway enterprise solution to energy efficiency and reduce energy consumption and a series of problems , has real meaning and value to the construction and development of high-speed railways.
