Abstract
The working principle of rotor hydraulic damper and its influence on rotor vibration are mainly studied,and the influence of hydraulic damping on helicopter rotor system vibration is theoretically analysed from the theory of dynamics and dynamic balance.And through the solution process of typical problems of dynamic balance in the field is summarised,the conclusion that the change of damping characteristics and performance parameters of the hydraulic damper of the rotor system will affect the vibration level of the whole rotor system is obtained.
