| 摘 要： | 通过理论分析与接触耦合,材料/几何非线性计算相结合,研究了螺栓-法兰连接结构的静刚度非线性特性.将螺栓-法兰连接结构抽象为一个力学元件;单轴拉伸时,荷载一位移曲线分为预压力释放段、弹性段和局部塑性段;而单轴压缩时,荷载一位移曲线不存在预压力释放段.特别地,同时对比拉伸与压缩荷载一位移曲线时,发现荷载一位移曲线表现出强烈...

| Abstract: | The static stiffness character of bolted flange was discussed,performing the nonlinear calculation considering the coupling of contact and material/geometry.In this article,the strcture of bolted flange was considered as a cell.In the case of uniaxial tension,load-displacement curve was divided into such three segments: segment of preload releasing,elastic segment and plastic segment.Whereas only elastic and plastic segments were found in uniaxial compression.Particularly,obvious difference between tension ... |
