摘要
小垂度水平悬索的自由振动问题是一个经典的问题。在Irvine经典理论的基础上,考虑了精确的悬链线形式的索构形,推导了小垂度水平悬索自由振动的解析解,该解理论上比Irvine的解析解更为准确,它相当于把Irvine的经典结果推广到悬链线型悬索情形。本文推导的解析解可以看作是对已有的理论的补充。
The problem of linear free vibration of horizontal suspension cables with small sag is a classical one.Based on Irvine＇s classical theory,a theoretically more accurate analytical solution of this problem is obtained by considering the more precise catenary profile.This can be regarded as an extension of Irvine＇s work to catenary cables with small sag.The results of this study can be treated as a supplement of existing work.
