Modern Methods for Low-Order Models in Nonlinear Structural Dynamics.

摘要

In 1995 we reported experimental results on chaos suppression (control of chaotic dynamics) in a nonlinear buckling elastic structure as well as anti-control of chaos in the vibrations of structure with dry friction. In 1996-1997 we have been able to achieve the suppression of chaotic dynamics for an impacting mechanical oscillator using a method based on the ideas in the ogy control of chaos theory. Impact in loose structural connections as well as in machine components such as gears have been shown to be a source of deterministic noise in these systems. The control of the impact chaos was effected using a digitally pulsed magnetic actuator.
