| 中文摘要: |
| 以一典型 PET 瓶为研究对象,建立了其结构模型,利用 ANSYS 加载垂直载荷时,基于屈曲分析得到了PET 瓶的理论轴向压溃载荷和临界点的变形。 试验测定了该 PET 瓶的轴向压溃载荷,进行了理论与试验比较。 结果表明,理论值与试验结果误差小,验证了理论分析的有效性。 利用 ANSYS 分析进一步研究了不同环状结构、不同尺寸和不同分布等对瓶轴向承载能力的影响,并分析了其变形特点。 |
| 英文摘要: |
| A kind of typical PET bottle was studied, and the corresponding structure model was built. When the vertical load was loaded using ANSYS, on the basis of buckling analysis, the PET bottle's theoretical axial crushing load and the deformation at critical point were obtained. The value of axial crushing load was measured by the experiment. The result of comparison between theoretical value and experimental value showed that the error is small and acceptable. The theoretical analysis was proved to be valid. By computing with ANSYS, the influences of different kinds of structure, sizes and locations of grooves on axial load bearing capacity were obtained. |
