基于车辆制动与启动原理，建立合肥南站的动力有限元模型，利用空间梁单元模拟车站的梁柱体系，利用空间板单元模拟楼板，并利用质量单元模拟节点质量；对每个轨道进行制动、启动、高速通过、低速通过4种激励方式，进行站房动力计算，得到候车厅的动力响应，并给出每种动力响应下的加速度时程曲线与各关键动力指标；通过时程积分的方法，得到了各种关键列车工况情况下，候车厅典型位置的动力响应曲线。通过频域分析方法，得到典型位置的加速度时程自功率谱密度函数，以此根据《城市区域环境振动标准》进行舒适度评估。结果表明合肥南站的候车厅舒适性满足规范要求。

A dynamic finite element model is established based on the principle of vehicle starting and braking.As for this model,the spatial beam element is used to simulate the columns and beams,the spatial plate element is used to simulate the floor,and the mass element is used to simulate the mass of nodes.Four kinds of incentive methods,inclu-ding vehicle starting,braking,running in high speed and running in low speed on each track are taken to analyze the station dynamic calculation,then record the dynamic responses of the waiting hall,and the acceleration time history curve and the pivotal dynamics index should be shown under each dynamic response.Next,the dynamic response curve of the typical representative positions of the waiting hall can be obtained under various pivotal working conditions of the vehicle by time-integration method.And then,the auto-power spectral density function of acceleration time course for the typical representative positions is acquired by frequency domain analysis method,with which and with measurement method for environmental vibration of urban area,comfortableness is evaluated.The results show that the comfortable-ness of the waiting hall meets the code requirements of vibration acceleration level.
