An efficient computational procedure for random vibro-acoustic simulations
We discuss a new method for handling random acoustic excitations. The idea is to approximate the cross power spectral density matrix of the response by a low rank matrix. We illustrate the low rank approximation can be computed efficiently by the implicitly restarted block Lanczos method. We give a theoretical explanation.
متن کاملCompact and Efficient Active Vibro-acoustic Control of a Smart Plate Structure
An effective wide band active control law through one kind of the Dynamic Vibration Absorber (DVA) is proposed and studied in this paper. With the help of mechanical impedance method, active DVA control law is formulated based on the passive mechanical model. The electrical DVA can generate multi-mode active damping to the structure. The host structure is an aluminum plate and acceleration sign...
متن کاملVibro-Acoustic Analysis of Acoustic Liners For MRI Scanners
Introduction Magnetic Resonance Imaging (MRI) scanners are popular medical diagnostic devices providing useful information about patients in a noninvasive manner. However, a disadvantage of MRI is the high level of acoustic noise generated during scanning, which is caused by the Lorentz forces acting on the gradient coils bound within an epoxy resin cylinder. As the gradient current switches di...
متن کاملPerforming acoustic, vibro-acoustic and aero-acoustic computations using MUMPS
This talk focuses on the direct solution of large complex indefinite unsymmetric systems, that arise in acoustic, vibro-acoustic and aero-acoustic simulations. These systems are structurally symmetric and may contain some large dense blocks, e.g. due to the selection of hybrid modal/physical representations in the model. The first part of the talk gives an overview of the experienced MUMPS capa...
متن کاملA novel computational procedure based on league championship algorithm for solving an inverse heat conduction problem
Inverse heat conduction problems, which are one of the most important groups of problems, are often ill-posed and complicated problems, and their optimization process has lots of local extrema. This paper provides a novel computational procedure based on finite differences method and league championship algorithm to solve a one-dimensional inverse heat conduction problem. At the beginning, we u...
