| 摘 要： | 本文从理论分析及模型风洞实验两个方面对机翼带外挂系统极限环颤振的次谐响应进行研究。在非线性气动弹性系统处于稳定极限环颤振条件下,借助于单自由度非对称分段线性振子的次谐分叉条件,本文建立了一种预估极限环颤振次谐响应存在区域的相对简单的分析方法。数值积分及模型风洞实验结果表明这种预估是正确的。

| Abstract: | The subharmonic response of limit cycle flutter of wing with store system is investigated by theoreticanalysis and experiment in this paper.Under the condition of stable limit cycle flutter of a nonlinear aeroe-lastic system,a relatively simple method,which can predict the regions of subharmonic response of limit cy-cle flutter of wing-store system,is developed by means of the subharmonic bifurcation condition of singledegree of freedom oscillator.The results of numerical integration and wind-tunnel test support the predic-tion. |
