Dynamics Modeling and Simulation for Flexible Wing

针对大展弦比机翼气动弹性问题,进行气动弹性工程化建模和结构动力学分析。应用气动弹性分析理论和方法,对弹性机翼进行有限元建模,动力学特性分析及结构弹性分析,并针对垂直阵风减缓进行讨论。运用CATIA,MSC.adams,MSC.nastran软件,对大型弹性机翼,进行结构模型建立、动力学与运动学协同仿真。仿真结果验证了该方法在工程上是有效的。

To explore the problem of aeroelasticity of flexible wing, the engineering aeroelastic modeling and structural dynamics analysis method were studied. By using aeroelasticity theory and method, structural modeling with FEM, structural dynamics and vibration mode were analyzed, and then problem of gust load alleviation for a large flexible wing was discussed. For a large flexible wing, structural modelling was set up and collaborative simulation of structural dynamics and movement were performed by using of software CATIA, MSC.adams and MSC.nastran. The simulation verifies the approach available and effective.
