TL;DR
This study uses numerical analysis to optimize bionic-inspired ceiling panels for better dynamic properties and airflow.
Contribution
The novelty lies in using bionic designs and numerical methods to optimize hole placement in ceiling panels for dynamic performance.
Findings
The study found how different hole shapes and materials affect natural frequencies and vibration modes of ceiling panels.
Airflow analysis revealed pressure variations based on hole area and velocity, aiding in resonance prevention.
Comparisons with solid slabs showed the benefits of perforated bionic designs in dynamic performance.
Abstract
In this study, a numerical dynamic analysis of ceiling raster panels was performed. The analysis was conducted on panels designed with inspiration from bionics. The purpose of the analysis was to enable optimisation of the location of the holes in the designed slabs in order to achieve the preferred dynamic properties, including the natural frequencies of the slabs and an appropriate airflow to avoid the occurrence of resonance. Three different types of panels were used and a total of fifteen panels were designed in terms of their geometry, with circular, elliptical, and hexagonal perforations, made of different materials: polypropylene PP, wood, and aluminium. Then, using the finite element method and ANSYS 2023 R1 software, the airflow over the ceiling panels and their natural frequencies and vibration modes were analysed. The analysis took into account not only the shape of the…
