ABSTRACT

Abstract

1

The overall objective of the proposal is to acquire a VICON 612 Motion Analysis System (MAS)

and to 1) integrate it into existing research setups of the PIs, 2) strengthen new collaborative

research among the PIs, 3) develop new measurement techniques, 4) integrate it into selected

undergraduate and graduate courses in the two departments of the PIs, and 5) make the equipment

available to other researchers at the University. A MAS uses high-resolution CMOS cameras to

capture pictures of a dynamical system when visible red digital LED strobes light up tiny retro-reflective

markers that are fixed on the system. Instantaneous three-dimensional coordinates of

each retro-reflective marker that is seen by at least two cameras are automatically calculated

using photogrammetry, and displacements, velocities, and accelerations of all makers are

available for performing dynamic animation and further signal processing for dynamics

characterization, damage detection, and control. Physically different from common point sensors

(e.g., accelerometers and proximity sensors) and profile sensors (e.g, video recorders), the MAS

offers simultaneous, non-contact, and accurate measurements of 3D coordinates of as many as

100 points on a mechanical system undergoing large motions.

This work will solve critical experimental issues and develop advanced

experimental techniques for the testing, design verification, damage detection, modeling, and

rapid prototyping of HFSs and other mechanical and aerospace systems. This work will advance

the knowledge of nonlinear statics, dynamics, control, and design of deployable/inflatable space

structures and other mechanical systems. The system will dramatically enhance

research-intensive learning environments for training engineering students in the areas of 1)

vibration testing and analysis of mechanical and aerospace systems, 2) testing and

characterization of deployable/inflatable space structures, 3) motion control of mechanical

systems, 4) design of active structures, and 5) modeling of human movement. The potential

impact of this work on the design of modern space, aerospace, mechanical, and civil systems is

expected to be very significant and broad.
