Novel phonon crystal deceleration pavement structure
The invention relates to a novel phonon crystal deceleration pavement structure. The novel phonon crystal deceleration pavement structure is formed by sequentially overlapping five base plates and four phonon crystal thin plates, wherein the base plates are solid rubber plates, and vehicles can stably run on the base plates, the phonon crystal thin plates are rubber plates, and cylindrical small holes are regularly distributed to serve as scatterers so as to form a periodic distribution energy band structure of elastic constants and density. The base plates and the phonon crystal thin plates are sequentially overlaid to form the composite elastic wave phonon crystal structure with periodically modulated body elastic modulus and mass density. Compared with the prior art, a three-dimensional photon crystal periodic composite structure is adopted, and energy dissipation and speed reduction effects on vehicles can be achieved based on periodic Bragg scattering and local monomer Mie scattering.
本发明涉及一种新型声子晶体减速路面结构，该新型声子晶体减速路面结构由5块基板和4块声子晶体薄板依次叠加组成，其中，基板为实心橡胶板，供车辆在其上平稳行驶；声子晶体薄板为橡胶板，并规律排布圆柱体小孔作为散射体，以形成弹性常数及密度的周期分布能带结构。将基板与声子晶体薄板依次叠加，组成体弹模量和质量密度周期性调制的复合弹性波声子晶体结构。与现有技术相比，本发明采用三维声子晶体周期性复合结构，基于周期性的布拉格散射以及局域性的单体米氏散射，对车辆能够起到消能减速作用。
