摘　　要：弹性体导弹的横向振动与刚体运动具有复杂的耦合关系,针对弹性体导弹高速飞行时产生的弹体横向振动,采用带尾部推力的欧拉-伯努力梁模型建立了弹性体导弹的横向振动模型。基于对该模型的分析,提出了一种自适应参数估计方法,对模型中的耦合参数进行修正,仿真结果表明该方法能够使耦合参数快速稳定地收敛到真值。There is a complex coupling relationship between transverse vibration and rigid motion of the flexible missiles. Considering the flexible transverse vibration generated when the flexible missile flies in a high speed, we built up a model for the transverse vibration of flexible missile by using Euler-Bernoulli theory. Some coupling parameters in the synthetic model were not certain because of the complexity of rigid and flexible coupling relations. In order to accurately modify the coupling parameters in the model, an adaptive parameter estimation approach was put forward. Simulation results demonstrated the effectiveness of the method.
