Vibro‐acoustic response of a simplified residential structure exposed to sonic booms. Part I: Numerical model.

摘要: This paper presents a numerical model to predict the vibro‐acoustic responses of simplified residential structures exposed sonic booms. The is validated experimentally in companion paper. dynamics fluid‐structure system, including their interaction, computed time domain using modal‐decomposition approach. In dynamic equations structural displacement expressed terms summations over vacuo modes vibration. pressures inside interior volumes are as acoustic rooms with perfectly reflecting surfaces. numerically finite element method. A shell was specifically derived components typical buildings, e.g., plaster‐wood walls, windows, and doors. for rectangular geometries analytical expressions. Using modal decomposition, system may ...
