摘　　要：多孔模型质量轻,且具有优秀的力热磁等复合性能。采用多孔模型有望突破传统设计极限,获得综合性能优异的机械部件,满足先进工业级产品对结构的极致物理性能追求。近年来,增材制造技术的发展与成熟,大幅推动了多孔模型的工业应用,多孔模型已经在航空航天部件、医疗器械等重要装备或仪器中发挥出独特且卓越的工业价值。因此,以多孔模型设计方法为落脚点,分别从基于几何建模的多孔模型正向设计方法、基于拓扑优化的多孔模型逆向设计方法2方面阐述相关工作。前者论述了多孔模型的离散体素表示、连续参数表示、连续隐式表示、其他及混合表示等建模方法,后者论述了多孔模型微结构单元优化设计方法、多孔模型结构设计方法,并探讨了2方面多孔模型设计的发展趋势。The porous models are of light weight and excellent composite mechanical,thermal,and magnetic properties.They are expected to break through the traditional design limit,to obtain mechanical parts with excellent comprehensive performance,and to meet the extreme physical performance pursuit of advanced industrial products.In recent years,the development and maturity of additive manufacturing technology have boosted the industrial applications of porous models,playing a unique and outstanding industrial role in aerospace components,medical devices,and other important equipment or instruments.This review focused on the design method of porous model,and described the related work from two aspects:the forward design method of porous model via geometric modeling and the reverse design method of porous model via topology optimization.In case of the former,the porous model modeling methods were discussed,such as discrete voxel representation,continuous parameter representation,continuous implicit representation,others and mixed representation,while the latter was expounded on in terms of the optimization design methods of porous microstructure units and the overall porous model structures,as well as the trend of porous model design from these two aspects.
