摘要

本文对受损伤自由-自由梁的结构动力响应进行了对比分析。本文所评估的动力响应包括损伤自由-自由梁的前十个固有频率和相应的模态振型。将损伤自由-自由梁的固有频率和模态振型与几何相似的未损伤自由-自由梁和未损伤悬臂梁的相似响应进行了比较。结果表明，损伤自由-自由梁的模态振型与未损伤悬臂梁的模态振型更相似，而与未损伤自由-自由梁的模态振型更相似。这种行为背后的可能原因也被讨论。

Comparative analysis of dynamic responses of a damaged free-free beam with geometrically similar undamaged beams

In this paper, comparative analysis of structural dynamic responses of a damaged free-free beam has been reported. The dynamic responses evaluated in this work include the first ten natural frequencies of the damaged free-free beam and corresponding mode-shapes also. Natural frequencies and the mode-shapes of the damaged free-free beam have been compared with similar responses of geometrically similar undamaged free-free beam as well as an undamaged cantilever beam. Results show that the mode-shapes of the damaged free-free beam resemble more with the undamaged cantilever beam rather than an undamaged free-free beam. Possible reasons behind such kind of behaviour have also been discussed.
