The invention provides a track damping effect monitoring method and system, and the method comprises the steps: obtaining a corresponding force signal through the detection of a load under a steel rail in a track through a load detection base plate device under the steel rail when a train passes through; meanwhile, a force response signal under the track roadbed slab when the train passes through is detected through the same load detection base plate device installed under the track roadbed slab, a corresponding admittance spectrum is obtained through calculation based on the collected force signal and the force response signal, and the vibration reduction effect of the track is judged based on a comparison result of the admittance spectrum and a preset reference admittance spectrum. As the load of the train during actual operation is directly detected through the load detection base plate device integrated below the track, the method can effectively detect the vibration reduction effect of the actual track, and the load detection base plate device is integrated below the track, so that the passing of the train is not influenced, and the detection accuracy is improved. Therefore, the method can be used for monitoring the vibration reduction effect of the track for a long time without stopping the track for detection.

    本发明提供一种轨道减振效果监测方法及系统,通过轨道中钢轨下的载荷检测垫板装置检测得到列车驶过时轨道钢轨下的载荷得到相应的力信号,同时通过安装在轨道道床板下相同的载荷检测垫板装置检测得到列车驶过时轨道道床板下的力响应信号,基于采集得到的力信号和力响应信号计算得到相应的导纳谱,基于导纳谱和预设的参考导纳谱的比对结果判断轨道的减振效果。由于通过集成在轨道下方的载荷检测垫板装置直接检测列车实际运行时的载荷,因此本发明的方法能够有效检测实际轨道的减振效果,并且由于载荷检测垫板装置集成在轨道下方,不影响列车通行,因此本发明的方法可用于长期监测轨道的减振效果,而无需停线检测。
