【Abstract】 Electrolyte fluid assisted laser drilling process is not only complex,,but also incluenced by many factors.This article established the processing thermodynamics model according to the characteristics of the electrolyte fluid assisted laser punching processing.The model considers the influence of the spatial distribution of laser beam and material phase change latent heat on the hole and shows the transient temperature field distribution and interface evolution process.Besides,analyzing temperature field simulation applying restart and life &death unit technology of ANSYS finite element software combining APDL programming language and put forward the influence rule of different technological parameter to the shape of the holes to provide theoretical references for the actual electrolyte fluid assisted laser drilling experiment to select the optimal process parameters.更多还原
