Rotating Ring with Thermo-Elastic Damping and Point Masses

摘要: Most of structures are inevitable for imperfections. In this regards, evaluation imperfection is more important sensitive devices such as the resonators high level accuracy. work, micro ring structure studied with arbitrarily located point masses. As a model, rotating thin used and heat conduction effects considered thermo-elastic damping effects. Using mode shapes ring, analytical model introduced. For analyzing structure, various Quality factor (Q-factor) studied. Furthermore, influences concentrated random masses by split natural frequencies.
