摘要
涡激振动是柔性结构易发生的气动弹性现象。本文通过风洞试验,研究了均匀流场中弹性支承的二维刚性模型的涡激力,提出了一种识别涡激力模型中未知参数的方法。用本文的方法,进行了三种钝体模型的风洞试验。
Vortex-induced vibration is one of recurring aeroelastic dynamic responses of flexible structures.In this paper,the parameters of a mathematical model, used to describe the vortex-induced motion of a rigid,elastically mounted bluff body are identified.A method to esti-mate these parameters using numerical technique and wind tunnel test results is proposed.Three models have been tested in this study.
