1) Pipe of annular cross section
同心圆环截面管道
2) circular cross-section tube with constriction
变截面圆形管道
3) circular hollow section
圆管截面
1.
Experimental research on three truss girders made with steel circular hollow sections(CHS) under static point loading at quarter span from either end is presented in this paper.
研究结果表明,弦杆钢管内填充混凝土可提高弦杆的抗压、抗弯和径向刚度,改变节点失效模式,提高节点强度和刚度;弦杆为钢管混凝土的桁梁试件与空钢管桁梁试件一样,结构破坏均是因节点失效引起的;由于弦杆管内填充混凝土提高了节点的强度和刚度,不仅受压的上弦杆而且受拉的下弦杆管内填充混凝土,都会提高圆管截面桁梁试件的整体承载力。
4) eccentric section
偏心圆截面
1.
Numerical simulation on cross wedge rolling of shaft parts with eccentric section;
偏心圆截面轴类零件的楔横轧成形数值模拟
2.
The aim of this paper is presenting a new methodology of cross wedge rolling of parts with eccentric section.
模拟结果表明,从起楔开始就将坯料轧制成偏心圆截面的偏心轴类零件的楔横轧工艺是完全可行的,而且具有轧制力小、变形容易控制等优点。
5) o ring
圆形截面环
6) Circular hollow sections
圆钢管截面
