摘    要:采用压电材料对结构进行振动主动控制已经进行了广泛研究,论文进一步采用压电材料改进超声速壁板结构的气动弹性颤振特性,研究中考虑压电材料力电耦合效应的影响.采用Hamilton原理和Rayleigh-Ritz方法建立壁板及压电材料整体结构的运动方程,采用超声速活塞理论模拟气动力,利用加速度反馈控制策略对压电材料施加外电压,获得结构的主动质量.求解运动方程的特征值问题获得固有频率,进而确定气动弹性颤振边界,分析了反馈控制增益对超声速飞行器壁板结构主动颤振特性的影响,研究表明,采用压电材料可以提高超声速壁板结构的气动弹性颤振特性.

关 键 词:超声速壁板  压电材料  主动气动弹性  颤振分析
