电磁阻尼器对机翼外挂系统颤振增益调度控制

Investigation of Wing/Store Flutter Semi Active Suppression with Coulomb Damper

分析了电磁阻尼器的减振机制，选择了电流为增益调度控制的可控量。建立了机翼外挂利用电磁阻尼器进行增益调度控制模型，仿真计算结果表明了方案的可行性，据此设计制造了机翼外挂颤振半主动抑制的实验模型及相应的控制电路系统，风洞实验结果表明，利用电磁阻尼器半主动控制技术，可使机翼外挂系统颤振在相当大的速度范围内受到抑制。

The attenuation characteristics of electromagnetic damper are analysed and control parameters are chosen for semi active suppression.The numerical simulation model of wing/store flutter semi active suppression system with electromagnetic damper is established.The results show that the scheme is feasible.The wind tunnel model for semi active suppression of wing/store with the damper and circuit system are designed and worked out.Suppression results of wind tunnel test show that the response of the wing/store flutter can be suppressed over a large speed range by using semi active suppression technique.
