Intelligent coarse particles for vibration reduction and power generation

Abstract

Intelligent coarse particles for vibration reduction and power generation sequentially comprise a concrete shell, a steel shell, a plurality of piezoelectric vibration reduction energy harvesters and an electric energy collection and conversion structure from outside to inside, and the two ends of each piezoelectric vibration reduction energy harvester abut against the steel shell and the electric energy collection and conversion structure correspondingly and are used for converting stress of the concrete shell and the steel shell into electric power. The electric energy collection and conversion structure converts electric power into stable electric energy and stores the electric energy. On the premise that the strength and rigidity are guaranteed, the concrete shell is printed through the 3D printing technology, the vibration force of an external structure is received, the piezoelectric effect is utilized, and the piezoelectric vibration reduction energy harvester, the energy converter and the energy storage element inside are combined to collect, convert and store vibration energy into electric energy; dynamic stress of an external structure can be directly reduced, the service life of the external structure is prolonged, harmonic oscillator vibration energy can be converted into electric energy through piezoelectric materials, waste can be turned into wealth, and the device is a green energy source.

Description

technical field [0001] The invention relates to an intelligent coarse particle for vibration reduction and power generation. Background technique [0002] In ballasted railways, as the train speed increases and the axle load increases, the ballast needs to withstand greater vibration energy from the sleeper, while the ballast has high rigidity, small dynamic strain, and low energy consumption. The vibration reduction effect is not obvious, and the vibration energy transmitted to the ballast bed is relatively large, which also accelerates the crushing rate of the ballast. In addition, the vibration energy received by the ballast cannot be collected and utilized. Contents of the invention [0003] The purpose of the present invention is to solve the shortcomings of the above-mentioned existing devices, and provide an intelligent coarse particle for vibration reduction and power generation, which has a concrete shell through 3D printing technology, and uses the piezoelectric ...

Problems solved by technology

[0002] In ballasted railways, as the train speed increases and the axle load increases, the ballast needs to withstand greater vibration energy from the sleeper, while the ballast has high rigidity, small dynamic strain, and low energy consumption. The vibration reduction effect is not obvious, and the vibration energy transmitted to the ballast bed is relatively large, which also speeds up the crushing rate of the ballast. In addition, the vibration energy received by the ballast cannot be collected and utilized.
