摘　　要：介绍了抽鞭现象的理论与试验研究情况,着重介绍了试验研究结果及抽鞭过程的能量方法与动量方法,以及近年来抽鞭过程理论研究的最新进展,总结出抽鞭现象的一般特点及影响因素,并指出抽鞭现象与大型柔性结构中存在的部分现象如大型伞伞衣顶部抽打、空中加油机软管的摆动等存在相似性,对抽鞭现象的研究有助于深化对该类现象的机理认识。After presenting the experimental and theoretical researches on whipcrack phenomenon,the current study gives a particular description of Krehl＇s experimental results,the whip models based on conservation of energy and based on conservation of momentum,and the current researches on this unique phenomenon.Finally,the characteristics of whipcrack were acquired,and the comparison between the whipcrack and other large flexible structures ＇swing phenomena such as the huge parachutes＇ whip or the ＂probe-drogue＂ in-flight refueling system＇s whip showed that there was much comparability,so the study of the whipcrack phenomenon will help researchers obtain a better understanding of these phenomena.
