Univ of Texas develops software to predict noise and vibration in automobiles

The University of Texas has developed software to predict noise and vibration in automobiles. Automated Multilevel Substructuring (AMLS) was copyrighted in 2000. The software divides the model of a car into sub-structures and solves them independently. A model that originally would have had 1e6 DOFs, can be reduced into 20 levels of 10e3 DOFs.

MSC released MSC.Actran

MSC Software has partnered with Free Field Technologies of Belgium, to launch a vibro-acoustic software package called MSC.Actran.

The software uses finite element formulation for the acoustic elements. It can be used to model sound radiation, propogation (can handle non-uniform mean flow which makes it suitable for studying exhaust systems), enclosed sound fields, locally and non-locally reacting liners (suitable for modeling seats), sandwich panels (can handle constrained layer damping).
