建筑墙体在隔绝噪声中起着关键作用,由于各种建筑设备管线在墙体上开洞较多,在已知期望隔声量的条件下,如何确定墙体上缝隙最大面积成为一项重要的课题.采用免疫算法建立了隔声计算模型,将预期的隔声量定义成目标函数,单层墙的厚度、面密度与杨氏模量定义成约束变量.运用Matlab编程实现了目标函数全局最大值的求解,从而确定达到该隔声量的墙体材料、厚度和构造大样.
Building walls play a key role in isolating noise. Due to the large number of openings in the walls of various construction equipment pipelines, it is important to determine the maximum area of the gap in the wall, given the expected amount of sound insulation The subject of this paper is to establish a sound insulation calculation model using immune algorithm and define the expected amount of sound insulation as an objective function.The thickness, surface density and Young’s modulus of a single wall are defined as constraint variables.The global maximum of the objective function To determine the amount of sound insulation wall material, thickness and structure of large sample.
