摘　　要：[目的]研究迎爆面和背爆面面板厚度、壁板折角以及芯层高度对碳纤维增强复合材料梯形波纹夹层结构抗爆性能的影响规律。[方法]首先,基于三维Hashin失效准则,利用软件ABAQUS中的VUMAT用户子程序接口,开发纤维增强复合材料损伤演化的子程序模块;然后,通过与公开文献中的实验进行对比,验证爆炸冲击载荷下基于所开发子程序的碳纤维增强复合材料动态响应仿真方法的有效性;最后,基于该数值方法开展碳纤维增强复合材料梯形波纹板的抗爆性能参数化研究。[结果]结果显示,相比增大迎爆面面板的厚度,增大背爆面面板厚度对夹层板抗爆性能的提升更为明显;芯层壁板折角从45°减小至30°时,其抗爆能力提高了1.3%,而当从60°减小至45°时,其抗爆能力提高了6.3%;芯层高度从8 mm增大至20 mm时,其抗爆能力提高了27.7%。[结论]所做研究可为碳纤维增强复合材料夹层结构的抗爆设计提供参考。[Objectives]The effects of the thickness of the face plate,angle of the wall plate and height of the core layer on the anti-explosion performance of carbon fiber reinforced composite trapezoidal corrugated sandwich structures were investigated.[Methods]First,based on the 3D Hashin failure criterion,a subroutine module of the damage evolution of fiber reinforced composites is developed using the VUMAT user subroutine interface in ABAQUS.Second,through comparison with experiments in the public literature,the effectiveness of the dynamic response simulation method of carbon fiber reinforced composites based on a development subroutine under explosion impact loading is verified.Finally,a parametric study on the explosion resistance of carbon fiber reinforced composite trapezoidal corrugated plates is carried out based on the numerical method.[Results]The results show that,compared with increasing the thickness of the blast face panel,increasing the thickness of the back blast face panel can improve the explosion resistance of the sandwich plate more obviously;when the folding angle of the core wall plate decreases from 45°to 30°,the explosion resistance increases by 1.3%;when it decreases from 60°to 45°,the explosion resistance increases by 6.3%;and when the core height increases from 8 mm to 20 mm,the explosion resistance increases by 27.7%.[Conclusions]The results of this study can provide references for the explosion-proof design of carbon fiber reinforced composite sandwich structures.
