Based on the Simulation Analysis of the Design Parameters of the Marine Turbocharger Welding Turbine
Friction welding process has been widely used in the field of mechanical processing.Marine turbocharger products have been widely used in friction welding process.In this paper,the welding turbine of marine turbocharger ro-tor system is studied,and the stress of welding turbine under chamfering of 3 mm,4 mm,5 mm and hole depth of 12 mm,16 mm,19 mm,20 mm and 25 mm is analyzed.The results show that the hole depth of the welded turbine can be selected from 12 mm to 16 mm,and the overall stress change trend of the turbine is relatively moderate,which is condu-cive to the accumulation of welding slag formed during welding processing.The chamfering has little effect on turbine stress by hole depth,but according to the processing experience,chamfering is recommended to be 4mm.The results of this study further determine the preliminary parameters of marine turbocharger welding turbine machining,which is of great significance to guide the friction welding process.
