| 中文摘要: |
| 结合“新工科”力学类人才培养体系的要求,开发了轻质结构材料力学性能虚拟仿真实验平台。该平台采用基于Unity3D的WebGL技术,能够开展轻质点阵夹层结构设计与力学性能的三维仿真实验;利用该平台学生可以进行轻质结构材料的设计流程训练、点阵夹层结构设计方法训练、点阵夹层结构力学性能实验表征方法训练,从而掌握轻质结构材料力学设计流程、设计方法以及设计原理,增进对轻质结构材料承载需求的了解。实验核心内容包括轻质结构材料典型单胞设计及力学性能实验表征,实验结果为满足承载要求的轻质结构材料尺寸及力学性能实验数据。实践证明,该虚拟仿真实验有效解决了新材料设计实验教学难度大、成本高、耗时长,以及实验资源匮乏、无法满足新时期本科教学的问题。 |

| According to the requirements of “new engineering” mechanics talent training system, the virtual simulation experiment of mechanical properties of lightweight structural materials is developed. WebGL technology based on Unity3D is used to simulate the design and mechanical properties experiment of lattice sandwich structure. The virtual simulation experiment technology is used to train the design process of lightweight structural materials, the design method of Lattice Sandwich Structure and the experimental characterization method of mechanical properties of lattice sandwich structure, so as to help students understand the mechanical design process, design method and design principle of lightweight structural materials. Through the analysis of the structural load-bearing characteristics, the load-bearing requirements of light-weight structural materials are sorted out, and the typical cell design and experimental characterization method of mechanical properties of light-weight structural materials are presented. Finally, the experimental data of the size and mechanical properties of light-weight structural materials meeting the load-bearing requirements are given. Effectively solve the difficulty of experimental teaching, high cost, long time, lack of experimental resources, can not meet the needs of undergraduate teaching in the new period. |
