DAMPING THE RADIAL VIBRATIONS AND SELF-HEATING OF VISCOELASTIC SHELL ELEMENTS WITH PIEZOELECTRIC SENSOR AND ACTUATOR

摘要

The forced resonant axisymmetric vibrations and self-heating of a closed spherical shell, an infinitely long cylindrical shell, and a ring with piezoelectric sensor and actuator are studied. The effect of the temperature dependence of the complex characteristics of the passive material on the vibration amplitude and self-heating temperature is analyzed. The possibility of active damping of these vibrations with piezoelectric sensor and actuator is shown.
