【摘要】:使用三維繪圖軟件PRO/E 5.0繪制出三維角聯(lián)鎖機(jī)織復(fù)合材料結(jié)構(gòu)模型,借助有限元軟件ANSYS Workbench對該結(jié)構(gòu)模型的彎曲疲勞性能進(jìn)行分析。在復(fù)合材料彎曲靜力學(xué)分析的基礎(chǔ)上,添加疲勞工具對復(fù)合材料的抗疲勞性能進(jìn)行分析,通過復(fù)合材料纖維、樹脂各自的壽命、損傷分布云圖分析復(fù)合材料的抗疲勞性能。結(jié)果表明:彎曲載荷作用下,復(fù)合材料與彎曲壓頭接觸的位置表現(xiàn)出更大的彎曲應(yīng)力;這些位置在較小循環(huán)載荷作用下較早發(fā)生破壞;與測試方向平行的緯紗較經(jīng)紗發(fā)生更嚴(yán)重的破壞。
[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.
