Analysis of Wear Behavior of Aeroengine Blade Parts by Vibration Rotary Mass Finishing
Vibration mass finishing has been applied to the finishing of aeroengine blades,and there are still problems of poor pro-cessing consistency and low efficiency.For these problems,based on the discrete element method and barrel finishing theory,a vi-bration rotary mass finishing plan for aeroengine blade parts is proposed.EDEM was used to simulate and analyze the wear of the part surface with time,and the influence of the embedding depth of the part and the barrel size(diameter、length)on the process-ing effect was explored.The results show that compared with traditional vibration mass finishing,the vibration rotary mass finish-ing can change the spatial position of the part in the medium flow field,which is beneficial to improve the consistency of the part surface.When the spatial position of the part changes slightly along the radial direction during the rotation,that is,the part is lo-cated at the position of the barrel axis,the processing effect of the part is better.By changing the barrel size,the processing effect of the part can be improved,the surface processing efficiency and uniformity of the part are comprehensively considered,and the best parameter range of the roller size is selected according to the simulation results:(90～100)mm,barrel length:(80～100)mm.
