基于热-流-固多场耦合的厚截面复合材料凝胶前后固化均匀性优化
Optimization of cure uniformity for thick-section composite materials before and after gelation based on thermo-fluid-solid multi-physics coupling
摘要
Abstract
To address quality defects arising from non-uniform temperature and cure degree fields before and after gelation in the curing process of thick-section composite materials,a multi-objective optimization approach for cure uniformity is developed.This approach utilizes a thermo-fluid-solid multi-physics coupled finite element model in conjunction with optimized Latin hypercube sampling(OLHS)to construct a radial basis function(RBF)surrogate model.The goal is to optimize the uniformity of temperature and cure degree gradients before and after ge-lation.Compared to the original design,the optimization results demonstrate a decrease in temperature gradients of 51.7%and 66.5%before and after gelation,respectively,and a reduction in cure degree gradients of 33.3%and 63.6%,respectively,with only a 6.7%increase in total curing time.The maximum temperature peak during the entire curing process was reduced by 8.8%.These results indicate that the proposed method can significantly im-prove the uniformity of curing before and after gelation.关键词
