摘要
研究静气动弹性问题一大关键是要解决流固数据耦合。本文采用Jameson的中心差分有限体积法求解Euler/N-S方程,以结构影响系数法计算结构的弹性变形,用三角元面积加权法和常体积转换法(CVT)实现流固力的耦合,用无限平板样条法(IPS)或者常体积转换法实现位移的插值,提出一种静气动弹性分析方法,并进行了弹性机翼的算例验证。
Realizing data exchange to reflect coupling between fluid and structures is essential to solving static aeroelasticity problems. A method is presented for static aeroelastic analysis of aircraft wings using Jameson's finite volume method to solve Euler/N-S equations, flexibility influence coefficient matrix method to calculate structural deformations, triangle area weighted method and constant-volume tetrahedron method to reflect coupling between fluid forces and structural ones and infinite-spline interpolation or constant-volume tetrahedron method to interpolate displacements.
