信号設備の振動環境調査

抄録

Signaling systems tend to be installed at a place where vibrations due to train passing are caused via rails, sleepers, and roadbeds. Therefore, it is necessary to design in consideration of the influence of vibration not to be damaged by vibration. In recent years, the installation environment of signal equipment has been changing due to the speedup of trains and changes in tracks and structures. However, the details of the propagation of vibrations to signaling equipments have not been investigated so far. Therefore, we investigate the current usage environment of signaling equipment to grasp the actual situation. In this report, we show the background of vibration measurement so far and the current issues, and report the construction of an unmanned measurement unit and the status of investigations to date.
