Flutter Analysis of a High-aspect-ratio Wing with External Store

  • 摘要: 基于哈密顿原理推导建立大展弦比带外挂机翼的动力学方程。为了分析大展弦比机翼特性,考虑了大展弦比机翼的平面内弯曲效应,将传统机翼的弯扭动力学方程扩展到大展弦比机翼的弯弯扭方程;利用Dirac函数考虑外挂位置的影响;采用拉格朗日乘子的方法考虑梁模型轴向不可伸缩约束。引入无量纲化参数对动力学方程进行无量纲化处理。基于梁模型的边界条件,利用伽辽金方法及主振型的正交性将偏微分方程离散为常微分方程,并改写成矩阵和状态方程的形式。利用K方法进行颤振计算,分析外挂参数如外挂质量、位置和转动惯量对机翼外挂系统颤振速度的影响,并分析了各种速度条件下的响应历程。
