Calculating the acoustic performance of cylindrical components
Aircraft, submarines, automobiles, pipelines, piping systems, ventilation ducts: acoustic modeling of cylindrical bodies and nonplanar systems is complex. Meanwhile, there is high demand from industrial companies to optimize their sizing. For example, they need to ensure the comfort of users in buildings and modes of transport, by optimizing the quantities of material or the weight of components. The CSTB makes it possible to control noise pollution and vibrations caused by sound propagation through these systems using the AcouCYL computing core. Designed by the CSTB, this tool allows for much faster analyses of performance than traditional finite element modeling. The CSTB offers a hybrid approach particularly suited to the acoustic analysis of pipeline components. Combining testing in a reverberation chamber and software simulation with AcouCYL, it offers precise and reliable results with optimum processing times and costs.
