Solid-liquid two-phase abrasive flow machining is a method to effectively polish the surface of Special-shaped surface parts. Based on the processing characteristics of the abrasive flow machining. The standard model and the pressure-coupled SIMPLEC algorithm are used. The shear force and velocity of the near-wall surface of the runner of the solid-liquid two-phase abrasive machining with different inlet pressure are analyzed. The numerical simulation results show that the inlet pressure has little effect on the velocity, and the shear force has a linear relationship with the inlet pressure. To obtain a better polishing effect, the outlet pressure can be appropriately increased.
In order to investigate the effect of abrasive flow on the polishing effect of mutant tube parts, this paper chooses the fifth-order mutant tube parts as the research object, and the abrasive flow analyzes and analyzes the polishing process of the fifth-order mutant tube parts, and discusses the micro- Processing mechanism. Based on the analysis of the dynamic pressure, velocity and turbulence kinetic energy distribution of the fifth-order sudden change of the flow conditions, the numerical simulation results of the fifth-order abrupt change of the abrasive flow were analyzed, and the different pressure conditions of the abrasive inlet Effect of abrasive flow polishing.
