拉挤工字形复合绝缘子芯体工艺过程的热传递和固化模拟
Simulation of heat transfer and curing of pultruded H-shaped insulator core rod process
摘要
Abstract
Finite element simulation of the pultrusion process of composite insulator cores is carried out by COM-SOL software,and this study aims to adjust and optimize the process parameters and provide reference for actual production.The curing exotherm of matrix resin is equated as an internal heat source,and the temperature field and curability field in the composite pultrusion process are coupled to simulate the temperature and curability changes at different locations of the core cross-section.By simulating and analyzing the difference between circular and H-shaped cross-section cores under the same process parameters,the effects of parameters were highlighted.The re-sults show that the H-shaped core exhibits a smaller temperature gradient,faster cure rate,and superior curability compared to the circular cross-section.The finite element simulation provides theoretical reference for the pultrusion process parameters of the H-shaped core.After applying the optimal process parameters obtained from the simulation to the actual production,a dense and uniform epoxy matrix composite core was successfully obtained,and the actual production results were consistent with the simulation conclusions.关键词
