摘要
本文提出一种求解气动弹性系统动态特性的准确方法——正交搜索法,它利用复变函数中解析函数保角映射的特性,沿复频率s的实部和虚部交譬搜索,逐步达到所求复方程的根。该算法能在计算机上实现,直观、简便、实用。
In this paper the authors propose an accurate method for determining dynamic characteristics of aeroelastic system, called Orthogonal Search Technique. According to the method to solve flutter equation is an iterative process. In every step. one searches along real and imaginary parts of complex frequency by turns in order to obtain such a complex number whose mapping is nearest from the origin of W-plane under given conditions. The process does not stop until the difference between solutions of two adjoining steps is less than a prescribed limit. The method is simple and easy to use. Furthermore it can be automatically executed in computer.
