Vibration Analysis of the Load on Helicopter Swashplate Rod
The swashplate rod is a key component of helicopter control system.The vibration environment of helicopter is quite complex.The natural frequency of the swashplate rod is generally low.So resonance occurs easily.Resonance could reduce control precision or even damage the whole control system.Established dynamic and mathematical model of swashplate rod.Analyzed the vibration characteristics.Obtained the natural frequency and vibration mode function of the rod.In the compression, tension and free state, the natural frequency of the rod is basically the same.Made flight experiment with a developing helicopter as object.Measured the load of the swashplate rod in flight conditions.Make Fourier analysis to the load.Obtained the frequencies of the load on the rod.The frequencies coincide with 1 and 2 times of the rotor speed.
