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。
