摘　　要：基于有限元理论,对机织间隔织物夹层结构复合材料进行分析,利用CATIA软件建立了复合材料模型。将该模型导入有限元软件ABAQUS中,并对复合材料的低速冲击过程进行了模拟计算。将模拟结果与低速冲击试验进行对比,结果表明,有限元方法模拟计算值与试验值总体变化趋势一致,且误差较小,验证了该有限元模拟方法的正确性和可行性,并探讨了复合材料受到冲击载荷时的内部应力变化趋势,为机织间隔织物复合材料的性能研究、结构设计和工程应用等提供了一定的理论基础。The woven spacer fabric sandwich structure composites was analyzed,a composites model was es-tablished by using CATIA software based on the finite element theory.This model was imported into the fi-nite element software ABAQUS,where the low-velocity impact process of the composite material was simu-lated and calculated.The comparison between the simulation results and the low-speed impact experiment shows that the simulated values of the finite element method are consistent with the experimental values,and the error is small.The correctness and feasibility of the finite element simulation method are thus veri-fied,and the variation trend of the internal stress of the composites under impact load is discussed,which provides a theoretical basis for the performance research,structural design and engineering application of woven spacer fabric composites.
