为了解决短吊杆内力识别困难的问题,该文以吊杆为研究对象,分吊杆两端固接及吊杆一端固接,另一端铰接等情况进行分析研究. 通过引入有效长度的概念,采用二分法解决了吊杆不同边界条件下超越方程的求解问题,并通过大量数据推导了有效长度与无量纲参数ξ之间的关系. 通过对短吊杆的弯曲刚度和边界条件识别两方面问题的分析研究,得到了满足工程精度要求的识别短吊杆内力的方法,很好地解决了短吊杆内力识别难的问题.
為瞭解決短弔桿內力識彆睏難的問題,該文以弔桿為研究對象,分弔桿兩耑固接及弔桿一耑固接,另一耑鉸接等情況進行分析研究. 通過引入有效長度的概唸,採用二分法解決瞭弔桿不同邊界條件下超越方程的求解問題,併通過大量數據推導瞭有效長度與無量綱參數ξ之間的關繫. 通過對短弔桿的彎麯剛度和邊界條件識彆兩方麵問題的分析研究,得到瞭滿足工程精度要求的識彆短弔桿內力的方法,很好地解決瞭短弔桿內力識彆難的問題.

In order to solve the the problem of the difficulty of recognizing the internal force of a short suspender,the idea of an equivalent length is introduced with different boundary conditions of a short suspender. In view of the suspender,series of simulation data are used and the relationship between the equivalent length and dimensionless parameters ξ are obtained. The method of recognizing the internal force of a short suspender considers the influences of bending rigidity. The method here provides a meaningful exploration on recognizing the internal force of a short suspender.
