摘要：
By virtue of the principle of dynamic absorbers and traditional damping rings, a new type of damping ring was proposed to suppress the vibration of a rotor-gear transmission system. Based on an experimental device for an aero-engine, the bending-torsion coupling dynamic model of the rotor-gear transmission system was established by using the lumped parameter method (LPM). The Runge-Kutta method was employed to work out the simulation results, and the dynamic response of the system was also analyzed in the working frequency range. On this basis, the influences of the damping ring's installation stiffness, installation damping and friction on the dynamic response of the system were then investigated respectively. The simulation results reveal that the new type damping ring has a significant effect on the bending-torsion coupling vibration of the rotor-gear transmission system in the high frequency range, compared to the traditional damping rings. In a certain range, it is helpful to suppress the bending vibration of the rotors and the torsional vibration of the gears in the high frequency range by increasing the structural parameters of the damping ring. The optimal design of the new type damping ring is important for the vibration suppression of the rotor-gear transmission system. © 2018, Editorial Office of Journal of Vibration and Shock.
