自动化建模与优化平台开发及其在切削吸能结构的应用
Development of an automated modeling and optimization platform and its application for cutting-type energy absorption structures
摘要
Abstract
Traditional optimization design is constrained by issues such as geometric parameterization and the generation of hexahedral elements,resulting in cumbersome processes and low efficiency.In order to standardize the development process and improve the efficiency of optimization design,the automated modeling and optimization platform based on the multi-objective optimization(MOO)system was built,which integrated modules such as geometry,finite element modeling,data processing,and surrogate optimization.The automated modeling module based on CAE was constructed with feature sections and mapping paths using cubic spline functions to achieve automatic geometric parameterization modeling.Furthermore,based on the sweep method and model decomposition method,an automated hexahedral mesh generation method based on the multi-section sweep method was proposed.Additionally,in the conventional optimization process based on surrogate models,automation was achieved from numerical calculation results extraction to surrogate optimization through data transformation and processing algorithms.The results show that the platform can establish finite element models with small geometric errors and high-quality elements.Overall,structural crashworthiness indicators are improved to a certain extent,significantly enhancing the efficiency of the optimization workflow.关键词
