Abstract

Materials and structures been unpredictable changed by sudden changes in temperature, alternation temperature and local temperature. The temperature change in structures´ surface may coursed by air friction or sunlight illumination in the aerospace environment. In this paper, modal analysis of cylindrical shell by ANSYS is proposed. Static force which been saw as the PZT patches´ acting force is added to the cylindrical shell´s internal surface. The frequency will be changed by the aeroheating environment and the force. And in this paper, a method to adding force to restore the frequency is proposed.
