摘要

研究制动力作用下车辆—结构耦合系统的分析方法。以刚体动力学方法建立车辆子系统模型，以振型叠加法建立结构子系统模型，以给定的制动加速度时程、简化的Kalker蠕滑理论和轮轨密贴假定分别定义纵向、横向和竖向轮轨间相互作用力，采用时程积分和时间步内的力—运动状态迭代方式求解运动方程。作为算例，研究了深圳地铁4号线、6号线列车制动于深圳北站时车辆—结构动力耦合系统的动力响应，并对车站结构关键部位的振动状态做出了分析和评价。

Abstract

The analysis method of vehicle-structure interacted system under breaking force is studied. The vehicle subsystem is modeled by the rigid-body dynamics method, the structure subsystem is modeled by the modal superposition method. The longitudinal, lateral and vertical wheel-rail interacted forces are defined by the given breaking acceleration history, the simplified Kalker Creep Theory and the Wheel-rail Corresponding Assumption, respectively. The equations of motion are solved by the history integral method and the force-motion iterations within time steps. As a case study, the dynamic responses of the Shenzhen North Station under the braking of the Metro Line 4 and Line 6 trains are calculated, and the vibration properties of some key structural parts in the station building are analyzed and evaluated.
