Paper Abstract

Smart structures are being increasingly applied in active vibration control. Typically, motion ranges produced in such systems are in the micro-range. This work proposes a mechanism to accomplish macro-motion ranges using smart materials. A new concept for automotive active suspension has been developed using smart structures featuring piezoceramics. A candidate design is analytically investigated for performance. The work presented in this paper includes the concept, its illustration, development of a design geometry based on this concept, and its finite element analysis and results. It is shown that by a proper synthesis of smart structure, macro-motion outputs needed for this application are possible.
