Proposal for Excitation Acceleration in Vibration Endurance Testing of Signalling Equipment

抄録

Signalling equipment is installed in positions where it is exposed to vibrations from passing trains transmitted via rails, sleepers, and roadbeds. The design of signalling equipment must therefore take this into account to prevent vibration-related damage. In recent years, the installation environment of signalling equipment has evolved due to faster train running speeds and changes in tracks and structures. However, the details of vibration propagation to signalling equipment have not been investigated so far. In addition to current issues, this paper reports on guidelines for vibration acceleration amplitude in vibration endurance testing.
