Vibration isolation-energy harvesting integrated device and floating slab track
The invention discloses a vibration isolation-energy harvesting integrated device and a floating slab track, and belongs to the field of vibration energy harvesting and vibration isolation. Comprising a main frame, a positive stiffness module, a negative stiffness module and a supporting platform, the supporting platform is installed on the main frame through the positive stiffness module and the negative stiffness module. Positive stiffness is provided through the positive stiffness module, negative stiffness is provided through the negative stiffness module, and quasi-zero stiffness vibration isolation is achieved through combination of the positive stiffness module and the negative stiffness module. The positive rigidity module and the negative rigidity module each comprise an electro-mechanical conversion unit, and vibration energy can be captured. The device captures vibration energy in a mode of combining electromagnetic conversion and piezoelectric conversion, converts the vibration energy into electric energy, further realizes power supply for a health detection system, is simple in structure, and conforms to the concept of low-carbon sustainable development. The method can be widely applied to rail transit and other fields.
