摘要： The present invention provides a track bed resonator arranging method, characterized by comprising:
step S 1, conduct vibration test on the track line and inside the building at the sensitive point near the track line that is greatly affected by vibration as the train passes through to obtain vibration data;
step S2, calculate and determine the arranging range of the track bed resonators based on the vibration data measured in step S 1;
step S3, perform frequency domain analysis on the vibration data of the sensitive points to determine the indoor vibration resonance natural frequency of building at sensitive point affected by train passing;
step S4, design the track bed resonators based on the indoor vibration resonance natural frequency, so that the natural frequency of the track bed resonator is equal to the indoor vibration resonance natural frequency;
step S5, arrange the track bed resonators along the extension direction of the track line on the track bed within the arranging range.-

摘要： The present invention provides a load dynamic monitoring pad device, equipment and load monitoring system, comprising a base plate installed between the track bed and the rail pad, a sensor fixing plate, a carrying pad, a plurality of pressure sensors, and a plurality of load transfer columns. The sensor fixing plate has a plurality of upward opening sensor mounting slots, and the carrying pad has a plurality of sensor limiting slots, which can be assembled with the sensor mounting slots to form a plurality of sensor accommodations, and each pressure sensor is accommodated in each sensor accommodations. The upper end of the sensor is in contact with the bottom of the sensor limiting slot, and the lower end is mounted on the track bed through a load transfer column and the base plate. Therefore, it is possible to monitor the pressure under the rail pads in real time through the pressure sensors. The pressure sensor is fixed and limited by the above method, which can avoid displacement, detachment, and other situations that may affect the monitoring effect due to track vibration during the monitoring process. It can be used for long-term monitoring.
