| 目的 基于胶接强度对铝蜂窝吸能特性的重要影响，利用铝蜂窝的最小周期结构——“Y”型单元研究铝蜂窝结构的异面压缩变形过程和能量吸收特性，以了解不同胶黏剂对铝蜂窝吸能性能的影响。方法 以Von Mises本构模型来表征胶黏剂的力学性能，建立一种含胶层的“Y”型单元有限元模型，模拟铝蜂窝结构的压溃变形过程，并得到胶层的变形和失效现象。结果 不同胶黏剂失效情况不同，与之对应“Y”型单元的平均压缩强度和能量吸能值也有区别。该模型能够有效地模拟铝蜂窝结构的压溃变形过程，并准确预报胶层的变形和失效。通过实验验证所建立的“Y”型单元有限元模型计算精度能够满足实际工程需要。结论 通过对“Y”形的单元准静态的压溃有限元模拟，选择了合适的胶黏剂制造铝蜂窝，并为后续包装缓冲件深入研究打下了基础。 |
| 英文摘要: |
| The work aims to study the process of axial compression deformation and energy absorption characteristics of aluminum honeycomb structure with the minimum periodic structure of aluminum honeycomb—"Y" shaped cell, base on the important influence of adhesive strength on the energy absorption characteristics of aluminum honeycomb, so as to know about the influence of different adhesives on the energy absorption characteristics of aluminum honeycomb. The Von Mises constitutive model was used to characterize the mechanical properties of adhesives. A "Y"-shaped finite element model with adhesive layer was established to simulate the crush deformation process of aluminum honeycomb structure, and the deformation and failure phenomena of adhesive layer were obtained. As different adhesives had different failure situations, the average compression strength and energy absorption value of the corresponding “Y” shaped cell would be different. The model could effectively simulate the crush deformation process of aluminum honeycomb structure and predict the deformation and failure of the adhesive layer accurately. The calculation accuracy of the finite element model of “Y” shaped cell established through experimental verification could meet the needs of practical engineering. Through the quasi-static crushing finite element simulation on the “Y” shaped cell, the suitable adhesive is selected for the production of aluminum honeycomb and the foundation is laid for the further research on the subsequent package buffers. |
