VA ONE 在船舶振动噪声领域的应用.pdf
主要介绍了VA ONE 在船舶振动噪声领域的应用，目录如下：
1.Introduction
2.Modelling the Structure
3.Modelling the acoustic fluid
4.Modelling the trim
5.Underwater Radiation
6.Air/Structure/fluid-borne Sources
7.Results examples
节选段落一：
One
(formerly AutoSEA2)
Modeling the structure
Creating panels from 2D CAD
Recent developments: a scripted HTML file allowing
user to click on 2D image creating nodes of the cabin
floor plan
A SEA subsystem is automatically created in VA One
environment
Creating panels from 3D CAD
Supported CAD format节选段落二：
Where:
Πt is the resonant or non-resonant power input* in receiver cavity
for the trimmed model
Πb is the resonant or non-resonant power input* in receiver
cavity for the bare model
b
tLogIL 1010
*Power inputs are standard results in VA One
Trim representation
Condensation method节选段落三：
In VA One, fluid loading adds a frequency-dependent
fluid mass loading to each panel.
