Abstract

The embodiments of the invention provide a floating slab track vibration isolator and a floating slab track vibration isolating system. The floating slab track vibration isolator includes a pluralityof vibration isolating assemblies, and the adjacent two vibration isolating assemblies of the multiple vibration isolating assemblies are connected by piezoelectric material plates; and one or more vibration isolating assemblies in the vibration isolating assemblies squeeze the piezoelectric material plates when a train travels, and the piezoelectric material plates generate electric energy by squeezing the vibration isolating assemblies.

Description

technical field [0001] The present application relates to the technical field of rail transit, in particular to a floating slab track vibration isolator and a floating slab track vibration isolation system. Background technique [0002] At present, the traditional floating plate track vibration isolator converts the vertical vibration energy transmitted downward when the train is running into the kinetic energy of the ring vibrator to realize the vibration reduction function. The suppressed vibration kinetic energy is usually dissipated in the form of heat energy, and there is no issues of further use. Contents of the invention [0003] The purpose of the embodiments of the present application is to provide a floating slab track vibration isolator and a floating slab track vibration isolation system, which are used to solve the problem that the vibration kinetic energy suppressed by the traditional floating slab track vibration isolator is usually dissipated in the form of...
