现代运输业开发创新的车辆设计，以满足日益增长的经济和性能需求。因此，越来越多的夹层构件被使用，这就需要新的连接技术。弹性胶粘剂的应用已被证明是一种适合于夹层板等大型构件的连接技术。上海跨快速磁浮列车、最先进的低地板索道车体壳体和船舶上部结构等混合结构的设计满足了严格的结构要求。本文介绍了弹性粘结在公共交通应用中的几个实例，并讨论了其设计特点、组装和试验。夹芯板的设计目的是为粘结层和荷载传递提供合适的区域。边缘加强板经过精心准备，使载荷能够平稳地转移到夹层壳体中。此外，还概述了胶粘剂层的设计极限。讨论了基于有限元方法的结构分析，并用试验结果对设计准则进行了验证。
The modern transportation industry develops innovative vehicle design to fulfill increasing economic and performance demands. Therefore more and more sandwich components are being used which require new joining technologies. The application of elastic adhesives has been proven to be a suitable joining technique for large-scale components such as sandwich panels. Hybrid structures, eg, the Transrapid Maglev train for Shanghai, state-of-the-art low-floor tramway body shells, and ship superstructures, have been designed to fulfill stringent structural criteria.This paper presents several case studies of elastic bonding in mass transportation applications, and discusses the design features, assembly, and testing. Sandwich panels are designed to provide a suitable zone for the bonding layer as well as for load transfer. Edge stiffeners are carefully prepared to enable a smooth load transfer into the sandwich shell. Furthermore, design limits are outlined for the adhesive layer. The structural analysis based on finite element methods is discussed, and test results have been used to verify the design criteria.
