The receptance characteristics of track system has been predicted with the three dimensional track for high frequency vibration, with this model, the structure parameters of track system affect onreceptance have been discussed. The results show that the stiffness of ballast, sleeper mass, and stiffness of railpad are the main factors affecting on resonance and antiresonance under second resonance frequency.

利用轨道系统高频振动模型预测了各种参数对轨道系统导纳特性的影响，结果表明：道床刚度、轨枕质量和轨枕垫刚度是影响轨道系统第二阶共振频率以下共振和反共振的主要因素，随道床刚度增加，或轨枕质量减小，或轨枕垫刚度增加，第一、二阶共振和第一阶反共振频率增加，道床阻尼、轨枕垫阻尼主要影响第一、二阶共振和第一阶反共振振幅，阻尼越大，共振峰值和反共振谷值越平缓。
