Structural Optimization Design and Finite Element Analysis of Turbine Pre-swirl Nozzle based on Selective Melting Manufacturing Process
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.
