【摘要】:使用三维绘图软件PRO/E 5.0绘制出三维角联锁机织复合材料结构模型,借助有限元软件ANSYS Workbench对该结构模型的弯曲疲劳性能进行分析。在复合材料弯曲静力学分析的基础上,添加疲劳工具对复合材料的抗疲劳性能进行分析,通过复合材料纤维、树脂各自的寿命、损伤分布云图分析复合材料的抗疲劳性能。结果表明:弯曲载荷作用下,复合材料与弯曲压头接触的位置表现出更大的弯曲应力;这些位置在较小循环载荷作用下较早发生破坏;与测试方向平行的纬纱较经纱发生更严重的破坏。
[Abstract]:The 3D angular interlocking woven composite structure model was drawn by using 3D drawing software PRO/E 5.0. The bending fatigue behavior of the model was analyzed by means of the finite element software ANSYS Workbench. On the basis of bending static analysis of composite materials, the fatigue resistance of composites was analyzed by adding fatigue tools. The fatigue resistance of composites was analyzed by the life of composite fibers and resins, and the damage distribution cloud diagram. The results show that the position of contact between the composite and the bending head shows greater bending stress under the action of bending load, and the failure occurs earlier under the action of small cyclic load. The weft parallel to the test direction has more serious damage than the warp yarn.
