Abstract
As an efficient urban transportation mode, subway has been developing rapidly in China, which provides convenience for people to travel and also produces certain vibration pollution. How to "turn this pollution into treasure" has become a widely researched problem for scholars. The advent of piezoelectric materials provides a good solution for the collection of vibration energy. In today's increasingly short of natural resources, if the vibration energy can be reasonably used, energy-saving benefits can be greatly improved. In this paper, the subway track vibration model was formulated which mainly considered the effect of vertical vibration on the track, moreover, the piezoelectric cantilever working mode attached to the rail was analyzed, together with the establishment of the subway track generator equipment model. In this paper, the matching rectifier, filter and boost circuit are designed and the software simulation is carried out. The simulation results showed that the scheme was feasible and available to provide reference for the application of vibration energy storage system for subway track.
