Date: January 14, 2004
Time: 10:30am
Location: NIA, Rm 404
Speaker: Haym Benaroya, Rutgers University
Subject:* "Reduced Order Models for Dynamics, Vibration, Design and Reliability"
Additional Information: Presentation (PPT)
In this talk I will summarize my research activities and interests in various detail, and discuss how these fit into the vision for NIA and the Langley Professorships. Also discussed are a vision for team building and outreach.
A brief outline of research is presented on: random differential equations, inverse problems in vibration, lunar bases and their design and reliability, and the space elevator. More details are given about the development of reduced order dynamic models of:
Vibration of imperfectly-periodic structures
Nonlinear dynamics of offshore structures to wave loads
Vortex-induced offshore structural oscillations.
The reduced-order model is very valuable as a first-order framework for understanding the essential dynamics of a complex system. We can begin to define the design space, the possible dynamics and stability, the importance of uncertainties and the effects of all these on design life and reliability.
This presentation briefly formulates several key engineering vibration problems and summarizes the insights derived from the model.
