Based on rail/wheel reaction and track/bride reaction theory and systems engineering theory, new vehicle-track and vehicle-track-bridge system dynamic models are established and discussed in details, including ballast track model and ballastless track model. The characteristics of the models are:(1) vehicle-track and vehicle-track-bridge system dynamic models are coupled in vertical and lateral;(2) track vibration on bridge is taken in account, track on bridge is considered as one or two layer continuous-point supported rail model, according to actual track structure, interaction between vehicle and bridge transfer from track structure;(3) three type of ballastless track models (tieembanked, elastic-tie-block, slab track) are presented;(4) models reflect the main feature of actual vehicle, track and bridge structure, the response computation frequency of models is relatively broad, which can be applied to analyze both low frequency and high frequency vibration.

基于轮轨相互作用和线桥相互作用特点，本文从系统工程角度出发建立了车辆、有碴轨道和无碴轨道、简支箱梁桥垂向和横向耦合系统动力分析模型，该系统模型具有以下特点：（1）车线、车线桥体系均考虑为垂向、横向耦合振动系统，车线间通过轮轨接触几何关系耦合，轨道与桥梁间通过轨道与梁体间的力与位移协调条件耦合；（2）充分考虑桥上线路在车线桥系统中参振作用，根据桥上线路轨道结构特点将桥上轨道结构模型具体化，即对桥上轨道结构视为多层支承体系，车桥间的动力作用通过轨道结构来传递；（3）建立了三种形式无碴轨道动力分析模型，即长轨枕埋入式、弹性支承块式和轨道板式无碴轨道模型；（4）系统模型详细，分析频带宽，适用范围较广。

Analysis result shows that the dynamic interaction between wheel and rail and the rail-pad force of the strengthened track are little bigger than those of the unstrengthened track,the safety grades of the tracks are same,the strengthened track can benefit to decrease the displacements of all components of track structure obviously,to restrain the deformation of track effectively,and to reinforce the stability of railway,especially the lateral displacement and the gauge enlargement of the strengthened rail are about 33% of original rail.

分析结果表明：强化后轨道结构的轮轨动态相互作用力及轨枕支点压力均较强化前的相应值略大，但皆属相同安全合格等级；强化轨道结构位移大幅度降低，有效抑制轨道结构变形，增强线路稳定性，尤其是钢轨横向位移和轨距动态扩大量较强化前下降十分显著，前者仅约为后者的1/3左右；强化轨道也有利于降低轨下结构振动和减轻列车提速后对轨下基础的破坏。

Wheel/rail noise of the high-speed slab track on concrete bridge and that of the urban elevated supporting block track are predicted respectively. Noise of the slab track, compared with that of the ballasted track, is more severe. The noise of the slab track is about 6.2dBA higher than that of the ballasted track for the receiver nearby the rail, and about 3.5dBA higher than that of ballast track for the receiver

对降低高速铁路桥上板式无碴轨道及城市轨道交通桥上支承块式无碴轨道轮轨噪声的技术措施进行了研究，包括：(1)分别就板式轨道和支承块式轨道结构参数的低噪声设计原则进行了研究；(2)对几种典型的新型轨道用吸声材料的降噪效果进行了分析，结果表明降噪效果显著；(3)就声屏障高度、位置、形状以及声屏障内侧敷设吸声材料对降噪效果的影响进行了分析，结果表明：声屏障越高、越接近轨道，降噪效果越好；声屏障内侧敷设吸声材料，可降低钢轨近旁噪声2.0～3.0dBA，可降低近地面噪声约1.5～2.0dBA
