实现轻量化、一体化航空航天零件快速制造

行业介绍 | Industry introduction

航天器每减重一公斤就可以降低发射成本2万美元,轻量化设计减重的每一克都意义重大。传统结构设计受限于传统加工工艺的加工能力,只能依靠经验与积累进行设计,常常存在受力不均以及材料分布不均等问题;基于金属3D打印技术,结合拓扑优化设计的优化结构,在满足功能及刚度的基础上,强度提升、局部应力降低,减重十分明显,受载更加均匀,实现了材料的均匀、合理分布;3D打印技术可以加工任意复杂结构,其制造成本独立于结构的复杂度,打破了传统加工工艺的桎梏,为结构的优化设计提供了更灵活的自由度,特别适用于拓扑优化设计复杂几何构件的加工。


Each kilogram of spacecraft can reduce launch costs 20,000 US dollars, lightweight design weight loss for each gram is significant. The traditional structure design is limited by the processing ability of the traditional processing technology and can only be designed by experience and accumulation. There are often problems such as uneven force distribution and uneven material distribution. Based on the metal 3D printing technology and the optimized structure of topological optimization design, On the basis of satisfying the function and rigidity, the strength is enhanced, the local stress is reduced, the weight loss is very obvious, the load is more uniform, and the material is evenly and rationally distributed. The 3D printing technology can process any complicated structure, the manufacturing cost is independent of the structure Complexity, breaking the shackles of the traditional processing technology, for structural optimization design provides a more flexible degree of freedom, especially for topology optimization design of complex geometric processing components.
