Verification of Vibration Reduction Effect of Helicopter Heading Control System based on Dynamic Characteristics Optimization
In view of the phenomena of fracture of the heading control pull rod support and large vi-bration of pedal in the rear cabin during flight of a helicopter,the mounting dynamic characteristics of the heading control system were optimized by increasing the counterweight of the heading control system and replacing part of the pull rod with a ball cable.The test flight verification results showed that the two methods could effectively reduce the vibration of the pull rod,and then significantly im-prove the vibration of the support loading and pedal.
