摘要
为保证高速铁路的安全优质运营,标准规定中应防止共振现象的发生。高速铁路共振按结构质量、作用位置等可分为车桥系统、弓网系统、轮轨系统和其他部件等4个类别,梳理高速铁路共振研究现状及相关标准规定,分析我国铁路工程标准设计执行标准的情况。通过国内外高速铁路相关标准对比发现,国内外主要共振标准的规定大体相当。现场试验数据表明:我国高速铁路车桥系统和弓网系统均不会产生共振现象,轮轨系统和其他部件在采取相关措施以后也不会出现共振现象。提出我国高速铁路有关标准仍需完善、基础理论研究尚需深化、系统配套研究需进一步加强等下一步工作建议。
As required in specification,resonance should be avoided to ensure the safe and high-quality operation of high-speed railway. This paper defines four resonance categories,namely vehicle-bridge system,pantograph-catenary system,wheel-rail system and components,epitomizes the status quo of HSR resonance research and the requirements in relevant standards, and analyzes the implementation of these requirements in standard design. The provisions about resonance are muchalike according to the comparison of Chinese high speed railway standards with those abroad. Tests results show that resonance would not occur in vehicle-bridge system and pantograph-catenary system,nor in wheel-rail system and components after proper measures are taken. This paper puts forward some suggestions on further researches such as modifying relevant standards,intensifying basic theoretical research and system supporting research.
