Vibration reduction and power generation sleeper based on resonance principle
The invention discloses a vibration reduction and power generation sleeper based on the resonance principle. The vibration reduction and power generation sleeper comprises an outer frame, a resonancebody and sealing plug blocks, a cuboid cavity is formed in the outer frame, the resonance body is arranged in the cuboid cavity, the sealing plug blocks are connected to the two ends of the cuboid cavity respectively, and the two ends of the resonance body are tightly attached to the sealing plug blocks respectively. The resonance body is formed by connecting a plurality of resonance units side byside, and each resonance unit comprises an upper stop block, a lower stop block, a support arm, a movable hinge, a spring, a high-density mass block and a piezoelectric material. On the premise thatthe strength and rigidity of the sleeper are guaranteed, the resonance units are arranged in the sleeper according to the resonance principle, the resonance units generate resonance counterforce on the sleeper under train excitation, the dynamic stress of the sleeper on a lower railway ballast can be directly reduced, and the service life of the railway ballast is prolonged; through structural design and optimization, the vibration reduction effect is enhanced by utilizing the mass amplification structure, and the harmonic oscillator vibration energy is converted into electric energy by utilizing the piezoelectric material, so that the electric energy can be provided for nearby power utilization units, and wastes are turned into wealth.
本发明公开了一种基于共振原理的减振发电轨枕，包括外框、共振体和封口堵块，外框内设置有长方体空腔，长方体空腔内设置有共振体，长方体空腔两端分别连接有封口堵块，共振体两端分别紧贴封口堵块，共振体由多个共振单元并排连接形成，共振单元包括上挡块、下挡块、支架臂、活动铰链、弹簧、高密度质量块和压电材料。在保证轨枕强度和刚度的前提下，本发明利用共振原理，将共振单元布置于轨枕内部，共振单元在列车激振下对轨枕产生共振反力，可直接减小轨枕对下部道砟的动应力，延长道砟服役时间；本发明通过结构设计与优化，利用质量放大结构增强降振效果，利用压电材料将共振子振动能转化为电能，可为附近用电单元提供电能，实现变废为宝。
