摘要
为实现减轻航空发动机涡轮预旋喷嘴重量、缩短制造周期,根据涡轮预旋喷嘴组件的结构和加工特性,基于选区熔化制造技术(SLM)对其进行适应增材制造工艺的结构优化设计,并对预旋喷嘴的增材制造过程进行有限元分析,探究预旋喷嘴的最优成型方向和在增材制造中的变形情况.后期制造表明,通过SLM增材工艺的预旋喷嘴结构优化设计,可获得17.08%的轻量化效果,缩短了制造周期,达到轻量化的目的.
Abstract
In order to reduce the weight and manufacturing cycle of pre-swirl nozzle of aeroengine,ac-cording to the structure and processing characteristics of the pre-swirl nozzle assembly of turbine,we have conducted structural optimization design adapted to additive manufacturing processes based on selective laser melting manufacturing technology(SLM).Finite element analysis has been conducted on the addi-tive manufacturing process of the pre-swirl nozzle to explore the optimal forming direction and deformation situation of the pre-swirl nozzle in additive manufacturing.Post production indicates that the light weight effect of 17.08%can be obtained by optimizing the structure of the pre-swirl nozzles based on SLM addi-tive manufacturing process,shortening the manufacturing cycle and achieving the goal of lightweight.
