摘要:
为研究管球组合试件在超低周疲劳试验中的变形特征,设计了三向支撑可单轴往复加载的试验装置。采用不同加载制度对钢管φ60×3.5进行超低周疲劳试验,得出了断口截面特征、中点的空间挠度和椭圆度、滞回曲线、断口环向壁厚分布规律。结果表明:中点处的椭圆度和空间挠度可以反映材料损伤过程,可通过这两指标为震后评定螺栓球网架杆件的工作状态提供参考;幅值改变会加速材料的损伤,同时当加载幅值恒定时材料的损伤也会随循环次数增加而缓慢积累;管球组合试件的滞回性能良好;断口截面形状、中点的空间挠度和椭圆度及断口环向壁厚变化也因加载制度不同而差异显著。
Abstract:
In order to study the deformation characteristics of the tube-and-ball joint specimen in the ultra-low cycle fatigue test, a three-way support can be designed for single-axis reciprocating loading.The ultra-low cycle fatigue test of steel pipe φ60×3.5 was carried out by different loading systems. The characteristics of fracture section, spatial deflection and ellipticity of midpoint, hysteresis curve and distribution of wall thickness of fracture were obtained.The results show that the ellipticity and spatial deflection at the midpoint can reflect the material damage process, and the two indicators can be used to provide a reference for evaluating the working state of the bolt ball grid member after the earthquake.Amplitude changes will accelerate the damage of the material, and when the loading amplitude is constant, the damage of the material will slowly accumulate as the number of cycles increases.The hysteretic performance of the tube ball test piece is good.The shape of the fracture section, the spatial deflection and ellipticity of the midpoint, and the variation of the fracture wall thickness are also significantly different due to the different loading regimes.
