研究了钢轨减振器抑制短节距钢轨波磨的效果。首先，进行钢轨振动现场试验，分析带减振器和不带减振器的钢轨的振动响应。其次，基于轮轨系统摩擦自激振动引起钢轨波磨的假设；建立并分析了轮轨系统和轮轨减振器系统的两个有限元模型。两组钢轨振动试验结果和理论结果均表明，钢轨减振器可以有效降低轮轨系统在200-800 Hz频率范围内的摩擦引起的自激振动，该频率范围对应于短节距钢轨波磨的频率。这可能是钢轨减振器能够抑制短节距钢轨波磨形成的主要原因。
The effects of a rail vibration absorber on suppressing short pitch rail corrugation are studied. Firstly, a rail vibration field test is carried out to analyze the vibration response of the rail with and without the vibration absorbers. Secondly, based on the hypothesis that friction-induced self-excited vibration of a wheel-rail system causes rail corrugation; two finite element models of a wheel-rail system and a wheel-rail-absorber system are established and analyzed. Both sets of rail vibration test results and theoretical results show that the rail absorbers can effectively reduce the friction-induced self-excited vibration of the wheel-rail system in the frequency range of 200-800 Hz, which corresponds to frequencies of short pitch rail corrugation. This may be a main reason that the rail vibration absorber can suppress the formation of short pitch rail corrugation.
