Abstract

The use of adhesive joints in various industrial applications has become increasingly popular due to their beneficial characteristics, including their high strength-to-weight ratio, design flexibility, limited stress concentrations, planar force transfer, good damage tolerance, and fatigue resistance. However, finding the best process parameters for adhesive bonding can be challenging. This optimization problem is inherently multi-objective, aiming to maximize break strength while minimizing cost and constrained to avoid any visual damage to the materials and ensure that stress tests do not result in adhesion-related failures. Additionally, testing the same process parameters several times may yield different break strengths, making the optimization process uncertain. Conducting physical experiments in a laboratory setting is costly, and traditional evolutionary approaches like genetic algorithms are not suitable due to the large number of experiments required for evaluation. Bayesian optimization is suitable in this context, but few methods simultaneously consider the optimization of multiple noisy objectives and constraints. This study successfully applies advanced learning techniques to emulate the objective and constraint functions based on limited experimental data. These are incorporated into a Bayesian optimization framework, which efficiently detects Pareto-optimal process configurations under strict budget constraints.

在有噪声的约束条件下对工艺设计参数进行贝叶斯多目标优化:工程设计应用
摘要 由于粘合剂接头具有强度重量比高、设计灵活、应力集中有限、平面力传递、损伤耐受性好和抗疲劳性强等优点,因此在各种工业应用中的使用越来越普遍。然而,寻找粘合剂粘接的最佳工艺参数可能具有挑战性。这一优化问题本身具有多目标性,既要最大限度地提高断裂强度,又要最大限度地降低成本,还要避免对材料造成任何视觉损伤,并确保应力测试不会导致与粘合相关的故障。此外,多次测试相同的工艺参数可能会产生不同的断裂强度,从而使优化过程具有不确定性。在实验室环境中进行物理实验成本高昂,而传统的进化方法(如遗传算法)又因评估所需的大量实验而不适用。贝叶斯优化适用于这种情况,但很少有方法同时考虑多个噪声目标和约束条件的优化。本研究根据有限的实验数据,成功地应用了先进的学习技术来模拟目标和约束函数。这些技术被纳入贝叶斯优化框架,从而在严格的预算约束条件下有效地检测出帕累托最优流程配置。
