基于增材制造特性的航空发动机叶片快速成型工艺技术研究
|
摘要
提出一种基于增材制造特性的航空发动机叶片快速成型工艺方法。从增材制造的材料成型特性入手,通过对喷射丝材成型机理的研究,从三维模型的预处理、成型零件的快速成型和后处理等3个阶段分析了成型工艺参数对成型质量与成型效率的作用关系,并建立了各阶段的优化方案。结果表明,该方法只需传统减材制造的1/5周期即可加工出精度达IT8,表面粗糙度在3μm以下的制品,对实现复杂异型结构产品的快速制造奠定了基础。
A rapid prototyping method for aeroengine blade was presented based on the additive manufacturing characteristics. The relationship between the forming parameters and the craft quality was established by analyzing the pre-treatment of the 3D model, the rapid prototyping and the post-processing of the forming parts. Meanwhile, the optimization schemes at each stage of this process was put forward on the forming mechanism of jet wire. The results show that the method can prepare products with a precision of IT8 and surface roughness below 3 μm in only 1/5 cycles of conventional materials reduction process. Therefore, the research of this technology lays a theoretical foundation for the rapid manufacturing of complex shaped products.
