    Abstract
  • The vibration control method with dry friction damping was put forward for the supporting structure system in high thrust-mass ratio turbofan engine. A dry friction damper with vibration absorption function was designed to enhance the damping characteristic of the supporting structure without loss of stiffness, and achieve vibration response control for the system. Influences of friction contact characteristic and dry friction damper structure characteristic on the damping effect were acquired in theoretical analysis and simulation calculation, and the damping design flow for supporting structure was presented. Results exhibited that vibration response was attenuated with the dry friction damper, and the damping effect could be optimized with reasonable design of friction coefficients and claw's width, which helped attenuate resonance amplitude of bearing house by more than one order in the example.
