摘要:
为了得到满足江门中微子探测器结构使用要求的连接节点,设计了一种有机玻璃与不锈钢的连接方式,根据不锈钢紧固件形式的不同,加工了3个节点试件.通过试验考察了节点试件的极限承载力及其在长期荷载作用下的受力性能,并利用ABAQUS有限元软件对节点试件进行建模分析.结果表明:有机玻璃在长期受力时会发生明显的蠕变,节点试件在极限荷载作用下为脆性破坏;节点试件的极限承载力都能达到设计荷载的2倍以上;有机玻璃上测点的最大应力为8.467 MPa.节点试件的加工过程中应避免不锈钢与有机玻璃的共同聚合,防止因变形差异而产生的初始缺陷,并且应满足温度和光照的要求.
Abstract:
In order to achieve the feasible joint for the Jiangmen neutrino detector, an approach to connect acrylic and stainless steel is proposed. Three joint specimens were manufactured considering the different forms of stainless steel fastener. The ultimate bearing capacity and the mechanical behavior under the long-term load of joint specimens are experimentally investigated. Modeling and analysis of the joint specimens are carried out by using the ABAQUS finite element software. The results show that the creep of acrylic is obvious under the long-term load and the joint failure is brittle at the ultimate load. The ultimate bearing capacities of joint specimens are at least twice as large as the design load. The maximum measured stress on acrylic is 8.467 MPa. In the process of joint specimens, the common polymerization of acrylic and stainless steel should be avoided for preventing initial defects caused by the deformation difference. Meanwhile, the requirements of temperature and illumination should be satisfied.
