| Abstract: | A new rotor/fuselage vibration isolator(NRFVI) can isolate entirely or partly the dynamic loads and moments F x,F y,F z,M x and corresponding M y generated by the rotor.This paper summarizes the basic design principle of NRFVI,design method and key technology,including the design for corrugated circle membrane and beam type anti resonant isolator. Bench test and analysis result prove that the vibration isolation efficiency and weight target meet the design requirement by the use of NRFVI. |
