Real-time vibration reduction method for subway station based on vibration propagation path
The invention relates to the field of urban rail transit vibration reduction, in particular to a real-time vibration reduction method for a subway station based on a vibration propagation path. The vibration reduction step comprises the step of arranging an active vibrator and an array type vibration sensor; when a vehicle passes through a station, vertical vibration generated by a train and a rail system is spread to a top beam along a middle column of the station and serves as a vibration source; the array type vibration sensors are used for monitoring vibration sources at corresponding positions; the electronic control hub performs preliminary analysis on the vibration data acquired by the array type vibration sensor, and judges whether the vibration peak intensity exceeds a threshold value or not; if the threshold value is exceeded, entering step 4, and if the threshold value is not exceeded, ending monitoring; if so, determining a real-time anti-vibration amplitude; and the driving vibrators on the main beam and the middle column perform reverse vibration. According to the method provided by the invention, invasion of train vibration to an upper building is effectively reduced; and the environmental noise problem caused by train vibration in the operation period is reduced.
本发明涉及城市轨道交通减振领域，是一种基于振动传播路径的地铁车站用实时减振方法。减振步骤包括布置主动振子及阵列式振动传感器；当车辆经过车站时，由列车及轨道系统产生的竖向振动，沿车站中柱向顶梁传播，为振动源；阵列式振动传感器对相应位置的振动源进行监测；电子控制枢纽将阵列式振动传感器所获取的振动数据进行初步分析，判断振动峰值强度大小是否超过阈值；若超出阈值进入步骤四，若未超出阈值监测结束；若超出阈值，确定实时反振动幅值；主梁及中柱上的主动振子进行反向振动。本发明所提供的方法有效减少列车振动对上部建筑物的侵扰；减少运营期因列车振动造成的环境噪音问题。
