摘要
通过采用拓扑优化设计及金属3D打印成型相结合的手段实现了支撑架底座的结构轻量化、刚度最大化设计成型。采用约束支撑底座的最大平均应力和体积范围,成功将体积减少了75%。然后通过3D打印成型制备了优化后的底座模型。结果表明,优化设计方法和3D打印技术相结合能够大大提升零件的设计效率,降低设计成本,缩短企业研发周期,是一种新型和有前景的零件设计、验证及成型一体化手段。
Topological optimization and 3D printing technology are used to achieve a lightweight structure and maximumstiffness of pedestal molding. The volume is reduced to 75% by limiting maximum average stress and the range of volumepercentage. The model is manufactured using metal 3D printing system. Result shows that： combining topologicaloptimization and 3D printing technology will tremendously promote design efficiency, reduce design costs and the R＆Dcycle, which is a promising integration method of part design, verification and molding.
