Abstract

A panel subjected to aerodynamic forces is a typical nonconservative structual system of two-dimension. When aerodynamic forces increase over the critical amplitude, the panel experiences the dynamic instability of panel flutter. This study concerned with the structual design improving the stability limit of a panel exposed to supersonic flow by means of adaptive structure with piezoelectric material. Piezoelectric material embeded in the host structure material was connected to resistance-inductance shunt circuit, and expected to work as passive dampers. Maximum critical flow velocity of panel were obtained by the optimization of the allocation and circuit parameter of piezoelectric passive dampers in the context of simple genetic argorithm. Effect of the method for nonconservative panel structure is demonstrated by numerical cases.
