基于固化变形分析优化设计抛物面反射器模具
Optimization design of parabolic reflector mold based on curing deformation analysis
摘要
Abstract
To address the curing deformation caused by the mismatch between the mould and the CTE of the structural member in the curing moulding,the vacuum infusion process is used to prepare the carbon fibre fabric re-inforced composite mould,and the sequential thermal coupling analysis method is used to analyse the influence of the moulds made of various materials on the accuracy of the curing moulding of the member.In view of the deforma-tion of the composite mould,the rib support structure of the mould was designed with the help of HyperMesh soft-ware,and the location and thickness of the rib plate were optimized.The results show that when the mould is made of composite,the difference in thermal conductivity of the mould components is not obvious,and the temperature distribution of the components is more uniform.Compared with steel metal mould,when the mould material is com-posite,the displacement and deformation of the member is reduced by 30%,and the Z-displacement is reduced by 46%.Compared with the composite mould without ribbed plate support,the displacement deformation of the rotating paraboloid was reduced by 13%,and the Z-direction displacement remained almost the same.关键词
