摘要
本文对等截面裂缝梁动力特性进行研究.首先,基于自由振动方程得到等截面多裂缝梁的动力特性;然后,基于动力特性识别基础数据,对等截面裂缝梁正问题的正确性进行了算例验证.
In this paper,the dynamic characteristics of cracked beams with equal cross section were studied.Firstly,based on the free vibration equation,the dynamic characteristics of multi-crack beams with equal cross section were obtained.Then,based on the basic data of dynamic characteristic identification,the correctness of the direct problems of cracked beams with equal cross section was verified by calculated examples.
