为了研究设备以单级、双层形式悬挂对高速列车垂向振动的影响，本文建立了车辆-设备刚柔耦合模型，获得了车体中部、构架上方以及设备的加速度频响函数。考虑了几何滤波效应，设备的连接方式（刚性、弹性）、连接刚度、连接位置等因素下车体与设备的耦合振动特性以及其相互影响关系。结果表明：速度作为几何滤波效应的影响因素，在研究车辆-设备耦合振动时必须要考虑速度的影响；车辆在6-12Hz范围内的振动响应受设备连接参数影响明显；在双层隔振系统中，框架更容易与车体产生耦合振动；当设备连接刚度为原始值时，车体中部响应较小，但双层隔振系统中设备会与框架产生耦合振动导致二者振动急剧增大；设备连接位置越靠近车体中部，车体的低阶垂向弯曲模态更易解耦，可以显著降低车体中部振动，同时使得车体的高阶垂弯频率最大提高0.4Hz。
Abstract
In this article, the rigid-elastic coupling vehicle-equipment system has been established taking the high speed train with multistage and suspension multi-equipment as research subject, and the acceleration frequency response characteristics above the car body center and bogie have been obtained. Also, the vehicle-equipment coupling vibration characteristic and interactional relationship has been researched under considering geometry filtering effect , the equipment connecting method (rigid, elastic), the connecting stiffness and the connecting position . The result shows that: the speed has an important influence on the vehicle vertical response; the connecting parameters mainly affect the vehicle 6-12Hz; the frame and the car body more easily generated coupling vibration compared to the equipment 1 and 2; the middle car body vibration became quite tiny while the equipment and frame have the converse result when connecting stuffiness are 1Kei（i=1,2,3）;The connecting position closer near the middle vehicle, the smaller the middle vehicle vibration, and the higher vertical bending frequency increases 0.4Hz at most.
