摘　　要：论文利用ABAQUS仿真软件分析了高强钢波纹夹芯结构在三点弯曲以及面内压缩时的力学响应.将计算结果与实验值和理论值进行了对比,验证了数值模拟的准确性.进而分析了芯板材料属性(高强钢DP900和普通低碳钢DC01)以及波纹芯板排列方向(横向、纵向)对夹芯结构力学性能的影响.分析结果表明DP900高强钢波纹芯板夹芯结构抗弯强度是DC01低碳钢夹芯结构的2.39倍,抗压强度是低碳钢夹芯结构的1.40倍,纵向波纹夹芯结构比横向波纹夹芯结构弯曲刚度高11.63倍.The three-point bending and in-plane compression of the high strength steel corrugated core sandwich structure was simulated by using the finite element software--ABAQUS. The calculated results were compared with the experimental values and the theoretical values. Then the responses of the sandwich structure under different core materials （high strength steel and carbon steel） and different direction were analyzed. The results showed that the bending strength of the corrugated core sandwich structure of DP900 high strength steel was 2.39 times higher than that of DC01 low carbon steel. And its compression strength was 1.40 times higher than that of DC01 low carbon steel. The bending stiffness of the structure in the machine direction was 11.63 times higher than that in the crossmachine direction.
