Considering the control requirements of fuselage vibration for a certain type of oil-electric hybrid unmanned aerial vehicle (UAV) during cruise phase,the damping vibration absorbers with 4-point and 6-point layout at the connec-tion between the engine and the fuselage are designed in this paper based on the passive vibration reduction princi-ple. After installing the two types of vibration absorbers,the flight state of the UAV are simulated on the ground,The experimental test result is compared with original vibration absorber. The results indicate that both types of vibra-tion absorbers can effectively control the fuselage vibration,and the damping vibration absorbers with the 6-point layout having a better effect of vibration reduction,which ensuring each indicator of the fuselage vibration meet the requirements. At the same time,the weight of the UAV has been reduced by reducing the weight of the vibration absorbers.
