摘要
This paper focuses on the experimental vibration analysis of the small-scale unmanned helicopter and the methods to weaken the influence for control design. The vibration source of the small-scale helicopter and the evaluation criteria are introduced. The influence of the main blades dynamic balance on vibration is analyzed and the way to decrease is presented; based on frequency domain analysis technology, the influence of the main rotor speed is well-analyzed and the method to optimize the rotor speed is proposed. The experimental results show that the analysis and the methods are effective and suitable for vibration reduction.
