Phononic crystal vibration reduction wall and method
The invention discloses a photonic crystal vibration reduction wall and method, and belongs to the technical field of vibration reduction walls. Comprising a wall body, the wall body is provided with phononic crystal units, and the phononic crystal units are arranged in an array mode in the height direction of the wall body; each phononic crystal unit comprises a plurality of phononic crystal unit cells, and the plurality of phononic crystal unit cells are distributed at intervals along the length direction of the wall body; wherein the two ends of each phononic crystal unit cell penetrate through the outer side of the wall body, the phononic crystal unit cells are horizontally arranged in the width direction of the wall body, and the distance between every two adjacent phononic crystal unit cells is at least 20 mm. The low-frequency broadband noise can be effectively regulated and controlled, the problems of low-frequency vibration and noise of a wall body caused by vibration of pipelines, equipment and the like can be effectively reduced, and the problem that the low-frequency broadband noise cannot be effectively reduced is solved.
本发明公开了一种声子晶体减振墙体及方法，属于减振墙体技术领域。包括墙体，所述墙体设置有声子晶体单元，声子晶体单元沿所述墙体的高度方向阵列设置；每个声子晶体单元内包括多个声子晶体单胞，多个声子晶体单胞沿所述墙体的长度方向间隔分布；其中，所述声子晶体单胞的两端均穿过所述墙体的外侧，且沿所述墙体的宽度方向水平设置，相邻的声子晶体单胞之间的间距至少为20mm。能够实现对中低频宽带噪声的有效调控，能够有效降低由管道、设备等振动引起的墙体低频振动和噪声问题，解决无法对中低频段噪声进行有效减振的问题。
