Based on damage theory and strain equivalent hypothesis,a fatigue model is presented in which the residual strain and stiffness degradation are included.
运用损伤力学理论,从应变等效性假设出发,基于复合材料结构"点应力"准则的概念,提出了一种考虑残余应变影响的刚度下降疲劳损伤模型。
2) decrease of stiffness of bent tube
压弯刚度下降
3) stiffness degradation experiment
刚度下降实验
1.

并采用多次卸载后加载的方法进行定扭角刚度下降实验,得到卸载后加载的剩余扭力矩,进而计算每次加载后的剪应变门槛值。
4) sudden drop of rigidity
刚度突降
5) reduce stiffness
降低刚度
6) sinkage stiffness
下沉刚度
1.
Further,the sinkage stiffness of the door is analyzed by using FEM,the result indicates that the deformation is graver near the top left comer of the door and the lower edge of the window,these parts should be enforced to optimize the structure.
再通过CAD/CAE接口,将车门的CAD模型导入到有限元软件ANSYS中进行有限元分析,主要是下沉刚度分析,结果表明门窗玻璃下边缘和车门左上角变形较大,可以考虑对局部加强,为改进设计提供科学依据。
