用电算法和实测法求悬臂结构动力特性参数

The Dynamic Character Determination of Cantilever Structures with Computer and Measure Method

本文介绍了求取弯剪悬臂结构动力特性参数的电算及实测方法,结合料仓、塔类典型悬臂结构,将电算结果与实测结果进行了分析对比,结果令人满意。电算法简单易行,在程序中只需令G=0(纯弯)和E=0(纯剪)便可用于纯弯、纯剪情形。实测法可适用于各种结构。

The dynamic character determination of bending-shearing cantilever structures with the help of computer and instrument is introduced in this paper, The computed results and the tested results of two ty pical examples of cantilever structures are compared and analyzed, It proved to be satisfied. The computation way is not only simple, but convenient also. It can be used in hoth cases of pure bending and shearing as we let E=0 (for pure shearing) and G=0 (for pure shearing) in the programme, the Measure method is suitable for nearly all of struoturee
