Cracked Engine Plate引擎板破损
center-cracked rectangle plate矩形裂纹板
eccentric cracked plate偏心裂纹
cracked-stiffened plate裂纹加强板
surface cracked plate表面裂纹平板
center-cracked plate带裂纹板
through-centre cracked plate贯穿的中心裂纹板
cracked plate with finite dimensions有限宽裂纹板
single-edge cracked plate单边裂纹板
A database of the relation between intact and cracked plate and mode and natural frequency is established. Compared the experiment with FEM numerical simulation, and evaluate errors in experiment data.
本文进行了悬臂板完好板和有裂纹板的模态试验,得到了完好板和有裂纹板的试验模态数据,并与有限元数值仿真结果进行分析比较,对存在的误差进行了分析。
