摘要
本文从实验方面来研究室外挂俯仰有预加载间隙对颤振的影响。风洞吹风中测出了单稳定极限环、双稳定极限环颤振的情况。实验结果与谐波平衡法计算值进行了比较。
The influence on flutter of external store with free-play in pich stiffness is investigated by wind tunnel test. Both single and double stable limit cycle flutter states are found. The results are comparable with that predicted by harmonic balance analysis.
