中文摘要:
      目的 研究高硼硅玻璃沙拉碗跌落冲击时的应力和变形情况,为沙拉碗安全包装提供参考。方法 运用Pro/E软件和Ansys软件建立沙拉碗及其缓冲包装三维有限元模型,对有无缓冲包装以及不同跌落高度和跌落姿态分别进行跌落仿真模拟,获取沙拉碗跌落冲击过程的应力、变形和加速度分布及变化规律。结果 沙拉碗跌落冲击时,最易损坏的部位在上部边缘、底部缓冲包装棱边及角的冲击部位;无缓冲包装时最大应力和脆值分别为76 MPa和1.84×105g,有缓冲包装时的最大应力和脆值分别为0.139 MPa和73.5g。结论 对沙拉碗进行包装设计时,应加强对上部碗口边缘部位和缓冲垫边角的保护;缓冲包装结构对沙拉碗起到了明显的保护作用,该研究为高硼硅沙拉碗缓冲包装的理论研究和结构优化设计提供了参考。
英文摘要:
      This research aims to study the stress and deformation of borosilicate glass salad bowl during dropping, and provide reference for safe packaging of salad bowls. The 3-D finite element models of the salad bowl and cushioning package were built with Pro/E and Ansys. Dropping tests of the salad bowl were simulated under different conditions: without or with cushioning package and from different dropping height and with different dropping angles, to get the simulation results of stress, deformation and acceleration of the salad bowl during the dropping tests. The upper part near the brim and the bottom near the shocking position were most likely to be broken. The maximum stress and fragility were 76 MPa and 1.84×105g without cushioning package and 0.139 MPa and 73.5g with cushioning package. More protection should be given to the upper brim and the bottom border and corner areas during packaging design for the salad bowl. The cushioning package can give effective protect to the salad bowl. The work provides valuable reference for the cushioning packaging theory and structure optimization of the borosilicate glass salad bowl.
