The vibration of plate and shell has been highly concerned 板壳结构的振动问题一直是研究人员关注的课题之一。
A new method to detect the damage of plate and shell subjected to multi - location damages is proposed 摘要提出一种适用于板壳结构的多位置损伤诊断方法。
Then , on the basis of the variation of the first mode , the new detecting method is put forward 以此为基础,提出基于一阶振型变化率的板壳结构的损伤诊断方法。
Therefore , researches of acoustics prediction and designing should be carried out with high demand 因此,有必要对板壳结构的声学预测和设计展开相应的研究。
Numerical example reveals that the new method can realize the multi - location damage detection of the plate and shell structure effectively , and at the same time simplify the process of the damage detection 算例表明该方法不仅可以准确地完成板壳结构的多位置损伤诊断,并且可以大大简化整个损伤诊断的过程。
