TOPOLOGY OPTIMIZATION METHOD AND DEVICE FOR ABSORPTIVE COMPLEX STRUCTURE DESIGN OF NOISE BARRIER
A method for optimally designing a phase to design a noise barrier adsorption composite structure according to an embodiment of the present invention comprises the following steps: calculating a physical property value of a porous sound adsorption material by using a Delany-bazley empirical formula; changing the physical property value of the porous sound adsorption material into a physical property value used for analyzing a finite factor in order to apply the physical property value of the porous sound adsorption material to sound analysis; analyzing a sound finite factor of a soundproof wall, to which the porous sound adsorption material is applied, by using the physical property value changed to be used for analyzing the finite factor; and designing a disposed structure of a rigid body applied to the soundproof wall and the porous sound adsorption material based on the analysis of the sound finite factor of the soundproof wall.
