摘要
In order to accurately predict the erosion rate of TC4 material under different erosion mechanisms, a multi-particle random erosion model was established by finite element method, and the erosion mechanism and erosion rate of TC4 plate under the erosion of Al2O3 particles with different particle shapes,impact angles and impact velocities were studied. Compared with the erosion rate obtained by erosion test under the same conditions, the rationality and authenticity of the numerical simulation model were verified. Results showed that cubic particles should be used in the simulation of low-angle erosion at 30 degrees,and the relative movement between edges and materials was more in line with the cutting process. Spherical particles should be used in the simulation of 90 degrees high-angle erosion,which can reflect the shearing and squeezing effects on the contact surface of pits during erosion. Under the same conditions,the greater the impact velocity of particles was,the faster the erosion rate increased,the faster the erosion rate increased at 30 degrees, and the more gentle the erosion rate increased at 90 degrees. © 2023 BUAA Press.
