摘　　要：为了研究纸浆模塑材料对打印机储运过程中的缓冲作用和力学性能,以打印机为研究对象,设计了打印机的缓冲单元,利用有限元分析软件对打印机缓冲单元静态堆码和动态冲击的力学性能进行了仿真分析。结果表明:打印机堆码单元的静态载荷为744.8 N时,缓冲单元最大应力出现在瓦楞纸箱上,最大应力为0.47 MPa,小于瓦楞纸板的极限应力2.38 MPa。打印机的缓冲单元以角接触跌落时的动态冲击最大,瓦楞纸箱的最大应力为6.25 MPa,超过了其极限应力,但下衬垫和打印机的最大应力分别为0.38 MPa和0.11 MPa,小于纸浆模塑材料和ABS的极限应力2.00 MPa和49.00 MPa。瓦楞纸箱吸收了冲击过程中产生的能量,对内装物起到了很好的保护作用。因此,利用纸浆模塑设计的缓冲衬垫,能够对打印机起较好的保护作用,提高了储运的安全性,更重要的是符合了可持续发展的绿色包装设计理念。In order to study the mechanical properties and buffering effect of pulp molding materials on printer during storage and transportation,the printer buffer unit was designed.Based on the technical parameters of the printer,the mechanical properties of static stacking and dynamic impact of the printer buffer unit were simulated and analyzed by using finite element analysis software.The results showed that with 744.8 N static load applied on the printer stacking unit,the maximum static stress appeared on the corrugated box as being 0.47 MPa,less than the limit stress of 2.38 MPa.When the printer buffer unit fell in angular contact,the maximum equivalent stress of the printer buffer unit was 6.25 MPa,exceeding its limit stress,while the maximum stresses of the lower pad and the printer were 0.38 MPa and 0.11 MPa respectively,less than the limit stresses of pulp molding materials and ABS of 2.00 MPa and 49.00 MPa.The corrugated box absorbed the energy generated in the impact process and played a good role in protecting the contents.Therefore,the cushion pad designed by pulp molding could protect the printer,improve the safety in storage and transportation,and more importantly,it conformed to the green packaging design concept of sustainable development.
