摘要
基于连续弹性离散点支承梁分析理论,采用瞬态动力有限元分析方法,分析轨道系统随列车速度、车辆荷载、车辆刚度及基础刚度变化时的瞬态动力响应。结果表明,列车激励频率和轨道系统频率决定了轨道系统的振动程度。
On the basis of the theory of continuous elastic discrete point supporting beam, the transient dynamic finite element method is used to study transient dynamic response of the track system with the change of the train speed, the vehicle load, the vehicle stiffness and the foundation stiffness. The results indicate that the exciting frequency of the train and track system frequency determine vibration level of the track system.
