8. 1. 2 Coupled acoustic-structural analysis of a speaker The entire speaker model is turned into a coupled structural-acoustic substructure using 150 extracted eigenmodes A substructure load case is generated to be used in the forced response analyses Results and discussion
Analysis of a speaker using Abaqus-Dymola co-simulation - Virginia Tech The structural-acoustic response of the diaphragm in the speaker assembly is modeled with its full three-dimensional finite element representation in Abaqus Explicit The Abaqus model and the Dymola model interact with each other through the co-simulation technique in the time domain
Acoustics Simulation for High-Tech - Dassault Systèmes The Abaqus Multiphysics FEA product suite from SIMULIA integrates noise simulation within the finite element solver, allowing fully-coupled structural-acoustic simulations to be performed within familiar Abaqus workflows
Estimating Acoustic Performance of a Cell Phone Speaker Using Abaqus we setup a dual-speaker model in Abaqus and compare the simulation results of the acoustic pressure at a certain distance in the exterior of the diaphragm when the speakers are excited by a mechanical force
Acoustic, shock, and coupled acoustic-structural analysis Abaqus provides a set of elements for modeling an acoustic medium undergoing small pressure changes In addition, Abaqus Standard provides interface elements to couple these acoustic elements to a structural model (see Choosing the appropriate element for an analysis type)
Abaqus Example Problems Guide (2016) This analysis of a speaker using the co-simulation technique between Abaqus and Dymola successfully demonstrates that the signal loss in the audible frequency range is negligible while maintaining the fidelity of original signal
