| 摘 要： | 间隙非线性对结构的气动弹性特性有重要的影响。传统线性气动弹性力学计算方法不能准确解决非线性系统的气动弹性问题。本文采用时域积分法计算舵面间隙非线性气动弹性,这种方法易于工程实现,为舵面系统(舵面与操纵机构)间隙非线性气动弹性稳定性和振动特性分析研究提供了一种有效的解决途径。

| Abstract: | The effect of freeplay nonlinearity is vital to aeroelasticity characteristic of structure,but normally computation method of linearity aeroelasticity can't settle this problem accurately.This article brings forward a new method of time threshold integration to compute the aeroelasticity with freeplay nonlinearity of the rudder system.This method is easy to accomplish and provides a new solving path for researching aeroelasticity with freeplay nonlinearity and libration character of the rudder system. |
