| Abstract/Description: | This thesis explores the effects of two assumptions commonly used in mathematical models related to a piezoelectric damping method known as State Switching. The technique relies on changing the stiffness state of a piezoelectric patch through control of the electrical boundary conditions. The transition between stiffness states is assumed to occur instantaneously and in concurrence with the switch event. In actuality, the transition will occur over a finite time and will trail behind the switch event by a finite time. For these assumptions to be valid, the effects of switch duration and delay on the performance of the State Switching method must be examined. In this thesis, the vibration reduction for various switch duration/delay values will be calculated using a numerical solver. The results of the simulations will be used to provide a range in which the two aforementioned assumptions produce negligible error, defined here as a 10% decrease in method performance. | |
