摘要
对影响高强度螺栓疲劳性能的材料、结构和工艺等因素进行了较广泛的对比试验研究。比较了6种材料疲劳试样的疲劳性能;考察了硬度、再回火、去应力退火、表面脱碳、滚丝/磷化的先后顺序、头下圆角粗糙度、滚丝轮螺纹牙形、头下圆角过渡形式等因素对高强度螺栓疲劳性能的影响。
Study is made on the influence of material, structure and process on the fatigue property of high strength bolt. The fatigue properties of six kinds of materials are contrasted.The influences of hardness,retempering,stress-alleviation an-nealing,surface decarburization,sequence of thread rolling and alramenting,roughness of underhead fillet,thread shape of thread rolling wheel,connecting form of underhead fillet on the fatigue property of high strength bolt are studied.
