| Abstract: | Aiming at the helicopter abnormal vibration fault reflected by the pilot in the outfield flight test of a certain helicopter,the vibration value of the fault location is measured by using specific equipment.Through analyzing the vibration spectrum and combining with the vibration characteristics of the helicopter,the fault causes are studied and analyzed.According to the measurement results and the suggestions of the maintenance manual of a certain helicopter,the measures to reduce the vibration value are formulated,and finally the abnormal vibration fault of the helicopter is eliminated. |
