摘要
在分析归纳喷嘴壳体组件制造难点的基础上,进行喷嘴壳体典型结构的性能提升和减重拓扑优化设计,并提出原始模型的增材制造优化设计原则,合理规划激光增材及切削减材组合制造的工艺次序及加工内容,极大压缩了加工工序及零件数量,有效减少了组合加工和焊接环节,提高了组件的结构强度及加工质量,降低了组件的结构复杂性、制造复杂性,可满足高性能喷嘴对先进制造工艺的发展需求。
On the basis of analyzing and summarizing the manufacturing difficulties of nozzle shell assembly, the laser additive manufacturing and traditional subtractive manufacturing were complentary to each other. A series of stable performance and topology optimization were designed and an optimization design principle of additive manufacturing for the initial model was proposed. The machining process optimizations for the body of nozzle under the combinative manufacturing was designed, which compressed the number of procedure and parts, reduced the link of combinative manufacturing and welding.The technology of laser additive and traditional subtractive manufacturing should meet the needs of aero-engine nozzle.
