基金项目:国家高技术研究发展计划(863)项目多材料多光源大型激光烧结成型装备及应用研究—快速模具制造工艺与性能研究项目资助(项目号:2015AA042503-2)以及陕西省自然科学重点项目糖基快速成型机理研究基金资助(项目号2012JZ7001)
中文摘要:
      通过对单颗金属熔滴沉积行为的研究,建立了三维实体零件搭接成形数值计算模型,探索了金属熔滴在小空间、大温度梯度环境下沉积成形中熔体流动、铺展、凝固成形机理,揭示了典型特征截面上搭接成形时,熔滴沉积中的主要特征因素与成形形貌、内部质量之间的影响规律,获得了最优的工艺窗口,为后续复杂金属件的熔滴液流沉积成形提供了技术支持和参考依据。

英文摘要:
      Based on single metal droplet deposition behavior research, and established the three-dimensional numerical calculation model of lap forming entity parts, explores the molten metal drop in little space, large temperature gradient in the sedimentary forming under the environment of melt flow, spreading, coagulation mechanism, reveals the typical cross section on lap forming, the main characteristics of droplet deposition factors and the influence law of forming between morphology, internal quality, obtained the optimum process window, for subsequent complex metal parts of molten drops flow deposits forming provides technical support and reference.
