| 针对显示动力学的分析方式技术上的困难，课题组提出了用静态结构分析的方式来代替显示动力学分析的方法。利用有限元分析模拟对双层GF/PP层合板的力学性能进行了探究，通过ACP（Pre）前处理模块实现了对GF/PP层合板的铺层设计，对双层单向GF/PP层合板采用静力学结构的分析方式表征其失效断裂，模拟得到的最大拉伸力和截面力相较于实际的拉伸力存在着误差率分别为7.76％和10.60％，在允许的误差范围内。通过对比双层单向GF/PP层合板静态结构分析和显示动力学分析的分析结果，验证了针对玻璃纤维增强聚丙烯层合板的拉伸失效断裂的模拟可以通过静态结构的分析方式代替显示动力学模拟的猜想。课题组的研究为初步探究多层单向层合板的拉伸失效断裂提供参考。 |

| In view of the technical difficulty of the analysis method of display dynamics, a static structure analysis method was proposed to replace the method of display dynamics analysis. The mechanical properties of double layer GF/PP laminates were explored by finite element analysis and simulation, and the lay up design of GF/PP laminates was realized through ACP (Pre) preprocessing module. The static structure analysis method was used to characterize the failure and fracture of double layer unidirectional GF/PP laminates. Compared with the actual existence, the maximum tensile force and section force deviation obtained by simulation are 7.76% and 10.60% respectively, which were within the allowable error range. By comparing the analysis results of static structural analysis and display dynamic analysis of double layer unidirectional GF/PP laminates, it is verified that the simulation of tensile failure and fracture of glass fiber reinforced polypropylene laminates can be replaced by static structural analysis. It provides a reference for the preliminary exploration of the tensile failure fracture of multi layer unidirectional laminates. |
