| 中文摘要: |
| 目的 研究小麦秸秆缓冲包装材料的力学性能。方法 分别对小麦秸秆缓冲包装材料进行静态压缩、 松弛蠕变以及动态压缩试验， 采用L-M非线性拟合法曲线以及遗传算法识别模型参数。结果 得到静态性能曲线和动态性能曲线， 以此建立小麦秸秆缓冲包装材料的力学模型。结论 小麦秸秆缓冲包装材料的力学性能曲线开口向上， 呈凹谷状， 且只有一个极值点， 具有明显的非线性及粘性特征。动态缓冲特性曲线近似呈U型， 过了最低点后， 曲线急速上升， 反映材料被压实。 |
| 英文摘要: |
| The aim of this work was to study the mechanical properties of wheat straw cushioning packaging material. Static compression, creep and relaxation as well as dynamic compression for wheat straw cushioning packaging material were tested. The nonlinear fitting method of L-M and genetic algorithm were used to recognize the model parameters. The static performance curves and dynamic performance curves were obtained, and the mechanical model was established for the wheat straw cushioning packaging material. The mechanical performance curve of wheat straw cushioning packaging material showed an upward opening and a valley shape, with only one extreme point. Besides, it had obvious non-linear and viscous characteristics. The dynamic cushioning characteristic curve had an approximate U-shape, and the curve increased sharply after the minimum value, showing the compression of the material. |
