摘要
针对大展弦比无人机低刚度特点,采用相位共振与相位分离一体化技术,研究了激振器附加质量、附加刚度、激励方案对大展弦比无人机模态试验的影响,有效提高了模态的识别质量和效率,具有非常重要的工程意义。
Large aspect ratio unmanned aerial vehicle (UAV) with low stiffness increases the sup- porting difficulty. The integration technology of phase resonance and phase separation has applied to study the influence of additional mass and additional stiffness on the test result. The research result has been applied in a certain UAV, and the test quality and efficiency have been improved.
