Abstract:
A thermal stress stiffening method for the vibration suppression of a rotating flexible disk with initial transverse runout is investigated via theoretical and experimental methods in this paper. This method generates in-plane thermal stress by heating the disk inner boundary, thereby enhancing the transversal bending stiffness of the disk and suppressing the transverse vibration. The thermal stress stiffenings influence on the natural frequency, dynamic stability and steady-state response of the disk with and without a mass-spring-damper system loaded is analyzed by theoretical computation.
