The objective of this project is to minimize the vibration and sound radiation from underwater shells using passive and active periodic stiffeners. A finite element model for the shell with the treatment was developed using MatLAB®, which was embedded in a C++ based SGI® Performer code that represents the core of the displayed model. In the virtual environment, the animated structure can be observed. The noise radiated can be identified using the sound system and the vibration of the shell surface can be recognized using the Touch Glove. (Project was funded by ONR).

In addition to modeling structural-acoustics in the virtual environment, collaborative modeling, design and visualization was also achieved with the Electronic Visualization Laboratory (EVL) at the University of Illinois at Chicago. Using the collaborative software (CAVERNSOFT) developed at the EVL. All the collaborating partners share the same information, in such a way that each one in the collaboration session can see avatars representing the other counterparts in his own CAVE. Each one can also communicate with the others and exchange information in real-time.

Noise levels inside helicopter cabins are extremely high. Therefore the objective of this project is to develop active and passive treatments for attenuating the vibration of the cabin structure as well the interior noise. In addition to the finite element and experimental work done on a helicopter, virtual modeling was also conducted for better visualization and deeper understanding. Modeling of the helicopter was completed using OpenGL. (Project was funded by ARO).

This project aims at designing twin-rotor extruders in a Virtual Reality environment in order to study the effect of changing the design parameters of the extruder on its mixing, vibration and noise radiation characteristics.
