Virtual Structural Dynamics, Acoustics and Control
Abstract
Equipment is needed to establish a Virtual Reality (VR) facility at the University of Maryland in College Park. The facility will enable engineers to Design, Simulate, Visualize and Test (DSVT) the dynamics, acoustics and controls of complex SMART structural systems in a virtual environment. With such facility, engineers will be immersed in an audio-visually coupled tele-operated environment whereby direct interaction with and control of the DSVT process can be achieved in real time. In this manner, the behavior of synthetic structural models can be monitored by literally walking through the structure and adjusting its design parameters as needed to ensure optimal performance while satisfying design and operational requirements. For example, engineers can move electronic wands to vary the number, size, type and location of sensors and actuators in a helicopter cabin, monitor the resulting closed-loop structural vibrations visually or by haptic feedback and simultaneously listen to the radiated sound pressure field. Such manipulations of the virtual smart objects in the scene are carried out while the engineer is navigating through the helicopter cabin to ensure that the vibration and sound levels, at any critical locations, are within the acceptable limits. The facility will serve also as a platform for virtual training of students and engineers on designing and operating complex smart structural controls on site as well as through collaborative efforts with other VR sites.
