中文摘要:
      目的 介绍包装件的跌落冲击研究现状。 方法 从跌落冲击机理、冲击动力学、试验和仿真模拟等方面详细讨论其发展现状,并指出各方面存在的问题。 结果 对于跌落冲击机理,太多的经验公式忽略了时间、阻尼、摩擦等因素的影响,物理试验不仅试验周期长、试验成本高,且很难观察到包装产品内部冲击后的变化特性,理论分析只局限于对简单的单自由度包装系统的研究,模拟仿真技术解决了物理实验和理论分析的弊端。 结论 目前的模拟仿真技术还很不成熟,很多数据库还未建立。
英文摘要:
      The research status of package dropping impact was introduced. The development status of package dropping was discussed in detail from four aspects, including dropping impact mechanism, impact dynamics, test and simulation, and the problems in every aspect were pointed out. The influences of factors such as time, damping and friction were neglected in many empirical formula about dropping impact mechanism; Physical test has a long test period and high test cost, and it is difficult to observe the internal change characteristics of packaging products after impact. Theoretical analysis is only suitable for studying simple single degree of freedom packaging system. The simulation technology solves the disadvantages of physical experiments and theoretical analysis. The simulation technology is very immature at the moment, and many databases have to be established in future.
