Abstract

Structural adhesive joints require high reliability. Thus, it is essential to bond the adherend under “bonding conditions” that can provide the required performance, including not only the initial properties but also changes over time. However, as the bonding conditions are dependent on multiple factors, the optimisation is complex. To address this multivariate problem, we constructed an experimental system that can autonomously search for the optimum “bonding conditions”. As a first step, the automation of thermal ageing and tensile tests for the characterisation of bonded joints was investigated. This was achieved using an automated testing system combining serial-link articulated robots, ovens, and tensile-testing machines. The effects of curing temperature and curing time on the initial strength were investigated experimentally, and the optimum curing conditions and the change in residual strength over time by thermal ageing were verified.

自动化单搭接热老化和拉伸试验

结构粘接要求可靠性高。因此，必须在能够提供所需性能的“粘合条件”下粘合粘合剂，不仅包括初始性能，还包括随时间变化的性能。然而，由于粘接条件依赖于多种因素，因此优化是复杂的。为了解决这个多变量问题，我们构建了一个可以自主搜索最佳“键合条件”的实验系统。作为第一步，研究了焊接接头的热老化和拉伸测试的自动化。这是通过一个自动化测试系统实现的，该系统结合了串行链接关节机器人、烤箱和拉伸试验机。通过实验研究了固化温度和固化时间对初始强度的影响，验证了最佳固化条件和热老化残余强度随时间的变化规律。
