| 摘 要： | 尝试了将磁流变阻尼器安装于机翼操纵面传动机构上的布局，并由此建立了非定常气动力下机翼-操纵面-传动机构的气动弹性动力学方程，利用on—off控制算法对系统进行颤振抑制，并且研究了控制延迟时间、控制电压以及阻尼器滞回宽度等参数对控制效果的影响。计算机仿真结果表明，控制延迟时间和控制电压对颤振临界速度有较明显的影响，而阻尼器的滞回宽度的影响不大，在本文的阻尼器安装布局和控制策略下，系统的颤振临界速度至少提高了17％。

| Abstract: | A typical wing aileron system with a rudder driver framework is investigated. The magenetorheological (MR) damper is fixed on the framework instead of the aileron rotation axis. A set of four-degree-of-freedom aeroelastic differential equations is developed and the on-off control algorithm is used to attenuate the vibration of the aileron. Numerical results show that the critical flutter speed is insensitive to the hysteresis of the MR damper. The higher apply voltage and the shorter control delay time can greatly increase the critical flutter speed. This configuration of the MR damper under the on-off control strategy can increase the critical flutter speed by 17% at least. |
