| 摘 要： | 本文提出一种颤振分析新方法－正交搜索法，其本思想是依据解析函数的保角映，沿复变量实部和虚部交替搜索，逐步达到所求方程的根。完全非定常气动力由格林九方法直接计算，颤振分析结果准确。该算法可在计算机上执行，有一定推广价值。

| Abstract: | In this paper,the author proposes a new method of flutter Analysis---orthogonal search method.'The method starts from con-formal mapping of analytic function and its searching process alternates between real and imaginary axes.For fully unsteady aerodynamic force is calculated with Green's Function method,the results of flutter analysis are accurate.Furthermore,the orthogonal search method can easily be executed on a computer. |
