摘要
通过研究弹性结构应变与位移的关系,得到了应变模态与位移模态的关系 借助此关系分析了几种常见约束下等截面弹性梁的应变模态。
Through the study on relationship between strain and displacement in the elastic strutures,the relation of strain modal to displacement modal was obtained.Based on it,strain modal of beam of equal section with several kinds of ordinary boundaries was analyzed which could help design the structure of beam dynamically.
