Abstract

The application provides an energy capturing and state self-sensing device, a structural design method and a system. The energy capturing and state self-sensing device is arranged in a floating slab track spring sleeve and is connected in series with a spring. Through collection and conversion of mechanical energy of spring vibration, self-power supply of the system is realized. Meanwhile, the high piezoelectric sensitivity of the piezoelectric ceramic is used to sense the mechanical state of the spring, thereby providing technical support for long-term online monitoring and intelligent operation and maintenance of key parts of the floating slab track.
