摘　　要：研究一种新型复合材料——低密度聚乙烯(Low-Density Polyethylene,LDPE)/聚氨酯(Polyurethane,PU),将其应用到包装箱领域.该包装箱通过旋塑工艺加工成型.通过单轴拉伸试验,分别测量出LDPE和PU的应力-应变曲线;根据旋塑模具设计要求用UG对包装箱进行结构设计;用ANSYS Workbench对该包装箱进行结构强度分析.仿真结果表明:LDPE/PU包装箱既保证结构强度,又满足轻量化要求,并能节约成本.A new composite material of Low-Density Polyethylene （LDPE）/Polyurethane （PU） is studied, which is applied to the crates field. The crates are processed by rotomolding. Through uniaxial tensile test, the stress-strain curves of LDPE and PU are measured. The crate structure is designed by UG according to the design requirements of the mould. The structural strength is analyzed for the crate by ANSYS Workbench. The simulation results show that the LDPE/PU crate can not only ensure the structural strength, but also satisfy the lightweight requirements and save the cost.
