| 摘 要： | 本文采用谐波平衡法,定量地解释了机翼颤振主动抑制风洞试验中出现的极限环现象。提出了比较精确的计及极限环基阶谐波与三阶谐波的分析计算方法。指出在采用液压舵机的情况下,伺服阀的不灵敏区是出现极限环现象的一个主要原因。

| Abstract: | The phenomena "limit cycle" occurred in wind tunnel test for active flutter suppression of a wing model are numerically explained using Harmonic Balance Method. This paper presented an analytical method with more accuracy than before considering the fundamental arid the third harmonic in limit cycle. In the case of hydraulic actuator the insensitive area of servovalve is the main cause for the phenomena "limit cycle" . |
