摘要:
针对3组应力比分别为0.3、0.5、0.8共24个材质为35K的8.8级M24高强度螺栓进行常幅疲劳试验和数值模拟,基于试验结果建立其相应的S-N曲线,并选取典型高强度螺栓疲劳断口进行宏观和微观分析,重点探讨了高强度螺栓预紧力缺失对其常幅疲劳性能的影响.分析结果表明:相同应力比和应力幅的一组螺栓,对应预紧扭矩变化100 N·m,其2×106次循环对应允许疲劳强度相差11.35%; 疲劳断口特征与预紧力大小明显相关,疲劳断口表面、扩展区和瞬断区范围随着预紧力增大,断口颜色变暗、扩展区范围扩大且瞬断区粗糙度加深; 高强度螺栓应力集中位置和大小受预紧力值影响较小,但与常幅疲劳试验断口位置基本吻合; 有无加荷装置对高强度螺栓应力大小影响明显,对应最大应力差值先减小后趋于稳定.
Abstract:
Constant amplitude fatigue test and numerical simulation were carried out on three groups of 24 specimens of grade 8.8 M24 high-strength bolts made of 35K under the stress ratios of 0.3, 0.5 and 0.8. The corresponding S-N curves were established based on the test results, and typical fractured high-strength bolts were selected for macro and micro fractography analysis, mainly focusing on the influence of the pre-tension loss on the constant amplitude fatigue performance. The analysis results show that: for one group of bolts under the same stress ratio and stress amplitude corresponding to the pre-tension torque change of 100 N·m, the difference between the allowable fatigue strengths at 2×106 cycles is 11.35%; the characteristics of fatigue fractured surfaces are obviously related to the pre-tension force, and with the increase of the pre-tension, the color of the fatigue fractured surface darkens, the area of the extension zone expands, and the roughness of the instantaneous fracture zone deepens; The location and magnitude of stress concentration of high-strength bolts are less affected by the pre-tightening, while the location generally agrees with the constant amplitude fatigue fracture location; the presence and absence of the loading device have a significant influence on the stress of the high-strength bolt, and the corresponding maximum stress difference first decreases and then tends to stabilize.
