Study on Virtual Simulation on the Comprehensive Mechanical Properties of Multilayer Property Composites

  • 摘要: 针对复合材料蓬勃发展的趋势与高等教育仿真实验教学“两性一度”的目标,从如何在有限的实验学时内向学生全方位展现新式复合材料的综合力学性能的角度出发,以Nomex蜂窝复合材料为案例,构建了基于Hypermesh/Dyna平台的虚拟仿真模型,模拟了酚醛树脂−芳纶纤维的多层属性复合材料薄壁性能。针对压缩、弯曲、冲击、剪切、拉伸、高速射击等实验的特点全面探讨了复合材料力学性能的虚拟仿真实验教学。研究成果对于虚拟仿真技术在复杂实验教学中的应用有指导意义。

     

    Abstract: In response to the booming trend of composite materials and the goal of “two properties and one degree” in higher education simulation experimental teaching, from the perspective of how to show the comprehensive mechanical properties of new composite materials to students within limited experimental time, a virtual simulation model based on Hypermesh/Dyna platform is constructed with Nomex honeycomb composites as a case to simulate the thin-wall properties of multilayer property composites with phenolic resin-aramid matrix. The mechanical properties of composite materials for the characteristics of compression is comprehensively discussed, including bending, impact, shear, tensile, high-speed shooting and other experiments. The research results are instructive for the application of virtual simulation technology in teaching complex experiments.
