高强度钢板U形件热冲压凹模结构拓扑优化
Topology optimization of hot stamping die structure on high-strength sheet metal for U shaped part
摘要
Abstract
To reduce the production cost and use cost of hot stamping die ,topology optimization of die structure was carried out based on numerical simulation about hot stamping .A finite element model based on thermal‐mechanical coupled method was created through the software ABAQUS , numerical simulation on high‐strength sheet metal for U shaped part's hot forming and cooling process was conducted .The contact stresses between blank and die at critical case were extracted to be the load for topology optimization ,and an optimization model which aimed to minimize structure volume with nodal displacement constraints on the die structure crucial areas was crea‐ted .Topology optimization of hot stamping die structure was carried out ,and the weight of die structure was reduced by 20% ,and die's stress and deformation almost kept the same with initial design conditions .T he research provides reference for the study of numerical simulation for hot stamping process and topology optimization of hot stamping die structure .关键词
