| 摘 要： | 气动结构耦合是研究静气动弹性问题的关键所在。采用三维Euler方程为控制方程,以有限元方法计算结构弹性变形,用细平板样条法(TPS)实现气动结构数据间的转换,进行机翼静气动弹性数值的模拟。算例结果表明,本方法是一种具有很高计算精度和工程实用性的气动弹性模拟方法。

| Abstract: | The coupling between aerodynamic and structure is essential to study static aeroelastic problems.In this paper,the governing equations used for the fluid flow are the three-dimensional Euler equations,the structural elastic deformation used for a numerical simulation of static aeroelastic for three-dimensional aircraft wing is a finite-element method and the exchanging data of aerodynamic and structure are achieved by a thin plate spline method.The results of computation show that the method developed in th... |
