摘要
通过求解基于三维非结构网格的欧拉方程计算机翼气动特性,采用结构柔度影响系数方法进行机翼静弹性变形的计算,利用三维非结构弹性网格技术进行几何外形变形下的网格修正,将以上三部分进行耦合迭代,实现了机翼的静弹性特性的数值模拟。采用开发的数值分析程序,进行了某支线飞机机翼静弹性特性的计算分析,计算结果合理,表明所发展的数值模拟方法可用于机翼静弹性气动特性的分析研究。
In this thesis,the aerodynamic characteristic of wing is achieved by solving 3D unstructured Euler equations, and by using the flexibility matrix the elastic deformations is calculated, the method of 3 D unstructured elastic mesh is introduced to modify the deformed mesh. Simulation of the static aero-elastic characteristics of wing is finished after coupling three forenamed approaches. The static aero- elastic characteristics of wing is analyzed and studied through developing our codes. The results are help to analyzing the static aero- elastic characteristics of wing.
