含裂纹梁的固有频率的计算

THE CALCULATION OF NATURAL FREQUENCY OF CRACKED BEAM

本文利用有限元法分别计算在不同的裂纹深度、不同的裂纹开口宽度的情况下梁的固有频率。并用实验验证了计算结果。

The natural frequencies of beam are calculated with finite element method in the cases of different crack width and different crack depth. The calculation results are proved by experiments.
