基于INGO-SVM的输电铁塔地脚螺栓螺母缺失无损检测方法

Gaoya dianqi
为了无损检测埋置于混凝土中的输电铁塔地脚螺栓有无螺母缺失缺陷，保障输电线路安全运行，文中提出了一种基于改进北方苍鹰优化算法（improve northern goshawk optimization，INGO）优化的支持向量机（support vector machine，SVM）分类检测方法（INGO-SVM）：首先，通过Cubic混沌映射与小孔成像反向学习策略增加北方苍鹰优化算法（northern goshawk optimization，NGO）种群的多样性，并在优化初始解的同时增加种群的搜索区域，

钢结构螺旋楼梯结构的直接分析法研究

钢结构螺旋楼梯因其特殊的异形结构受力复杂，使得传统线性分析法不能准确预测其力学响应进行稳定性设计，尤其是在确定计算长度时。研究采用直接分析法来克服这些限制，考虑了结构整体性和构件的初始缺陷，为分析和设计这类结构提供了一个高效且安全的方法。以一个具体工程为例，使用NIDA软件进行了直接分析法的稳定性研究，并将所得结果与线性分析法的结果进行了对比。研究考察了在全跨满载、左半侧满载、右半侧满载以及不同扇形组合活荷载分布下的力学响应，以及不同支座条件对楼梯结构响应的影响。结果表明 ...

Research on the load-bearing capacity and defect sensitivity of three-dimensional lattice cylindrical shells under axial compression

世界航天已经进入了大规模深空探测的新时代，对承载人类驶向星辰大海梦想的重型运载火箭，在干质比、可靠性和轻量化设计方面提出了更高的要求。为此，迫切需要发展更为高效和可靠的全新结构设计理念，促进超大尺寸重型运载火箭结构设计的重大变革。三维点阵夹层壳因其抗弯刚度高、轻量化空间大和多功能性一体化等优势，是应用于重型运载火箭壳体的一种潜在的结构形式。然而，当前制约其工程应用主要有三个方面：第一，三维点阵夹层壳体结构制备工艺不成熟，特别是制备空间的约束导致难以一体化成型大尺寸试样 ...
