二维固-固Suzuki晶格声子晶体薄板 弯曲振动特性的研究
Study of the bending vibration characteristic of two-dimensional solid-solid Suzuki phase phononic crystal thin plates
摘要
Abstract
The band gap structure and transmission characteristics of the bending vibration for Suzuki phase phononic crystal thin plates were calculated through the finite element method . The influence of the filling fraction and thickness on the band gap of Suzuki phase phononic crystal plate was discussed . Results show that there is a vibration band gap in the Suzuki phase phononic crystal thin plate , and a complete band gap and multiple directions band gap below 5000 Hz when the scatterer density is large . The band gap's width become large with the increasing of the thickness of the plate , and with the increasing of the filling fraction , the width of band gap firstly increased and then decreased .关键词
