Periodic box girder structure with oscillators arranged on diaphragm plate
The invention relates to a periodic box girder structure with oscillators arranged on a diaphragm plate, and the periodic box girder structure comprises a plurality of basic units; each basic unit comprises a top plate and a bottom plate, two webs are arranged between the top plate and the bottom plate, and the top plate, the webs, the bottom plate and the webs are sequentially connected to form abox type structure; a transverse partition plate is inserted into the box-shaped structure to divide the interior of the box-shaped structure into two spaces; at least one oscillator is installed onthe transverse partition plate, and each oscillator is embedded in the transverse partition plate in a wrapping mode through elastic light filler. The box-type structure is extended along the direction z perpendicular to the cross section to form a periodic box girder, and then the periodic box girder can be regarded as a local resonance phononic crystal, has an elastic wave band gap, and can be used for vibration reduction of building structures such as bridges and the like.
本发明涉及一种在横隔板上安置振子的周期箱梁结构，包括若干个基本单元，每个基本单元包括顶板以及底板，在顶板与底板之间布设两块腹板，顶板、腹板、底板以及腹板顺次连接形成箱型结构；在箱型结构内插设横隔板，将箱型结构内部分隔形成两个空间；横隔板上安装至少一个振子，且每个振子通过弹性轻质填充物包覆嵌设在横隔板上；该箱型结构沿着垂直于横截面的方向z进行延拓成为周期箱梁后可视为局域共振型声子晶体，具有弹性波带隙，可用桥梁等建筑结构的减振。
