研究了复合材料固化阶段的多目标优化问题。优化的目的是通过选择适当的热剖面，最大限度地减少固化过程的持续时间和固化部分的最大温度超调。所开发的方法结合了传热问题的有限元解和遗传算法。该优化算法成功且一致地逼近了多目标问题在各种变厚度特征几何中的Pareto最优前沿。结果突出了与标准工业固化曲线相比的效率机会。在超厚部件的情况下，在超调和14小时方面的改进可达70%。与传统的固化型材相比，超厚部件的加工时间可以缩短。在厚件的情况下，可以在温度超调和工艺持续时间内减少高达50%。(C) 2016年作者。Elsevier Ltd.出版。
This paper addresses the multi-objective optimisation of the cure stage of composites manufacture. The optimisation aims to minimise the cure process duration and maximum temperature overshoot within the curing part by selecting an appropriate thermal profile. The methodology developed combines a finite element solution of the heat transfer problem with a Genetic Algorithm. The optimisation algorithm approximates successfully and consistently the Pareto optimal front of the multi-objective problem in a variety of characteristic geometries of varying thickness. The results highlight the efficiency opportunities available in comparison with standard industrial cure profiles. In the case of ultra-thick components improvements of up to 70% in terms of overshoot and 14 h in terms.of process time, compared to conventional cure profiles for ultra-thick components, can be achieved. In the case of thick components reduction up to 50% can be achieved in both temperature overshoot and process duration. (C) 2016 The Authors. Published by Elsevier Ltd.
