在自主设计的试验设备上对双螺栓连接结构进行横向交变载荷下的松动试验,研究拧紧方式、载荷水平和材料配副等因素对松动的影响.结果表明:拧紧方式和载荷幅值对松动影响明显.相同实验参数下,双螺栓结构中同一螺栓的预紧力损失分散性大,不同螺栓的松动程度差异更大,一般靠近加载端的螺栓松动程度大.采用铝/钢配副比钢/钢配副预紧力大从而防松效果明显.

经验不确定分布一致性检验是在不确定分布未知的情况下,利用专家经验数据对不确定分布进行推断的一种非参数检验方法,是不确定统计领域参数估计和回归分析的基础和前提.本文主要研究了几种专家经验不确定分布的一致性检验方法.首先,简述了不确定统计和专家经验数据的基本理论;其次,利用专家经验数据系统分析了两组专家的经验分布是否存在显著性差异的Mann-Whitney U检验法、Kolmogorov-Smirno
散裂中子源利用荷能质子轰击重核后产生高通量中子,慢化器是调控中子的关键部件.此前国际上用铆钉铆接镉皮和铝合金部件,存在慢化剂泄漏的潜在风险,同时,铆钉铆接处也给物理建模增加了难度.常规电镀的镀层厚度是微米级,在活性的铝合金上施加一层厚达1mm的镉镀层难度很大.本文介绍了铝合金上电镀厚镉的无氰电镀方法、参数.本文的技术已经成功地制造中国散粒中子源氢慢化器和水慢化器的耦合层.
