SYSNOISE是集成在新版的软件包里,界面和功能强大很多,lms virtual.lab 8b的帮助文件就有2.6*GB之多.

FEM Coupled Tutorial

Objective:

The goal of this tutorial is to calculate the acoustic response of a coupled car compartment. In the first step, a document with the structural car biw model and its modes set will be prepared. In the next step, the acoustic response for the interior of a passenger car along with the structural surrogate mesh will be computed using the Vibro-Acoustic Response Analysis Case.

Pre-Requisites:

Software Configurations and Options that are needed to run the tutorial:

Configuration: Interior Acoustics, Option: NASTRAN Interface, Vibro-Acoustic FEM Solver, Acoustic Harmonic FEM Solver.

Tutorial Data Files:

• biw.op2
• FORCES.idx
• forces.ix0
• forces.ix1
• FORCES.mtx
• forces.dat
• Cavity.bdf
• Surrogate.bdf

[All data files can be found on the Getting Started Data-DVD, in VAM-Tutorial-Data\FEM-Tutorial. For ease of use, it is best to copy all files to a local folder.]

Note: In this tutorial, LMS Virtual.Lab will drive LMS SYSNOISE, so it is necessary to set the path to the SYSNOISE executable on your machine correctly. This can be done in ToolsOptionsAcousticsLMS SYSNOISE.
