Abstract

Thermally induced vibrations of a smart beam are investigated. The smart beam refers to an aluminum structure with an integrated active control sys- tem consisting of piezoceramic sensors and actuators. A simply supported aluminum beam is used to illustrate the nature of thermally induced vibra- tions caused by a suddenly applied heat flux. A distributed piezoelectric sensor/actuator pair is used to actively suppress the motion caused by ther- mal disturbances. The effect of large temperature changes on the structure
