| 摘 要： | 通过对玉米秸秆包装容器材料进行静态压缩试验,得到了材料的泊松比、弹性模量等基本参数,以及材料的力变形曲线,并在参数及模型的基础上对包装容器进行有限元分析.通过有限元计算,得到了压缩载荷作用下包装容器的应力分布规律、刚度与破坏强度,并且确定了包装容器最易出现裂纹的位置,计算结果与试验结果吻合较好.

| Abstract: | The basic parameters of plant straw packaging container,such as Poisson ratio,elastic modulus and so on,were gained by means of static compression test.The mechanical model was established from the force-deformation curve,and the packaging container was also analyzed through finite element method(FEM) based upon parameters and the model above.Some parameters such as the stress distribution law,stiffness and breaking strength under compression load were obtained and the easy-crackled position was also determ... |
