摘要
以某型号水槽式洗碗机为研究对象,设计缓冲运输包装并进行仿真计算。依据缓冲包装设计“六步法”,进行产品流通环境分析、确定洗碗机易损件及脆值,选用密度为25 kg/m~3的EPS为缓冲包装材料,设计缓冲运输包装方案。首先通过不同应变率的材料试验,完善LS-DYNA材料模型;然后基于LS-DYNA对包装件进行有限元仿真分析,结合相关测试标准,对包装件分别进行10种工况跌落仿真分析。结果显示:面跌落最大响应加速度为38.4g,棱跌落最大响应加速度为26.7g,角跌落最大响应加速度为23.6g;各工况最大响应加速度均小于产品许用脆值61g。所设计的包装方案满足运输过程中对产品的缓冲需求。
A certain model of sink-type dishwasher is taken as the object of study,for which cushioning transportation packaging is designed and simulation calculations are carried out.Following the“six-step method”of cushioning packaging design,the cushioning transportation packaging scheme is designed by analyzing the distribution environment of the product,determining the fragile parts and brittle value of the dishwasher,and choosing EPS with a 3 density of 25 kg/m as the cushioning packaging material.Firstly,the material model of LS-DYNA is perfected through the material test of different strain rates,then thefinite element simulation analysis of the packaging parts is carried out based on LS-DYNA,and the simulation analysis of three kinds of working conditions of the packaging parts is carried out respectively in combination with the relevant test standards.The results show that the maximum response acceleration of prismatic fall is 38.4g,the maximum response acceleration of angular fall is 26.7g,and the maximum response acceleration of face fall is 23.6g.All the maximum response acceleration of each condition is less than the permissible 61g brittle value of the product,and the designed packaging solution meets the buffer demand of the product in the transportation process.
