地铁列车与城际铁路列车的耦合动力响应分析
|
摘要
以天津市津滨轻轨下穿城际铁路工程为研究背景,基于ABAQUS显式动力分析模块建立了三维有限元与无限元相结合的模型,通过多点输入方式实现了列车荷载在空间的移动,计算了高速列车以不同速度运行、单列地铁列车运行、两列地铁列车相向运行耦合等不同工况下体系的振动响应,对比分析了不同工况下的加速度和位移响应.
Based on Jinbin mass transit under-crossing intercity rail,the multi-vibration calculating model of finite element and infinite element was created based on the ABAQUS/Explicit module,and train loads were imported by the multi-point input method.Besides,the dynamic response of the surrounding environment under the condition of high-speed train in different speed,single subway train vibration,two subway train coupling vibration etc.were calculated,and the acceleration and displacement in different conditions were analyzed.
