Parametric Response Surface Optimization of Acoustic Black Hole Beam Structures Based on Semi-analytical Method
摘要
Abstract
Acoustic Black Hole(ABH)has a wide prospect of applications in the field of structural vibration and noise reduction because of its wide frequency band and high efficiency,simple and flexible implementation method.In this paper,a one-dimensional ABH beam is taken as the object.Combining the semi-analytical modeling calculation method and response surface optimization method,the influences of five parameters,namely,characteristic length of the ABH,truncation thickness,power law,the characteristic length and thickness of the damping layer,on the damping effect of the one-dimensional ABH beam are analyzed.With the damping effect of the 1D ABH beam as the optimization target,the structural parameters of the beam and the damping are optimally designed.The optimized 1D ABH beam structure has an average acceleration level reduction of 19.03 dB in the frequency range of 10-8 000 Hz.This study is of a reference value for the engineering application of 1D ABH beam structure design in the field of vibration damping.关键词
