纸浆模塑结构单元的斜度与缓冲性能的仿真研究(英文)

Emulation study on the taper angle of structural unit and the cushion performance for the molded paper pulp

利用有限元分析软件，针对纸浆模塑典型结构单元，应用双线性运动增强型材料模型，进行系统力学分析，以力学分析得到的纸浆模塑缓冲结构单元的静态压缩曲线为基础。得出了缓冲包装结构拔模斜度对缓冲性能存在较大的影响，斜度在 4°～8°时缓冲性能最佳的结论。研究结果能为缓冲包系统的设计提供一定参考。

Abstract： A method was given to use ANSYS software to analyze the structure of cushion package, build the bilinear kinematics hardening molded and make a mathematical analysis for different structural unit of the molded paper - pulp. Based on the encapsulate curve of structural unit for the molded paper pulp, relationship of the taper angle of structural unit was revealed for the molded paper - pulp and cushion performante, and it was found that the best taper angle of structural unit is 4°～8°.
