Optimization of Structures with Passive Damping and Active Controls
Abstract
Vibration suppression may be approached in three ways: by optimal distribution of structural mass, by viscoelastic damping treatments, and by active feedback control systems. Software design tools that address all three approaches are needed for SDI structures so that each approach can be exploited with minimal weight penalties. This report documents development in structural optimization under dynamic loads, both steady-state and transient. New methods for these problems are derived and demonstrated on small-scale structural models. The methods address minimization of structural mass subject to constraints on peak responses in either domain, together with frequency constraints and side constraints on member sizes. The methods are exercised with and without active control systems. Keywords: Optimization, Structural dynamics, Damping, Control systems.
