Abstract

To fully understand the electrochemical machining profile, a multi-physics coupling simulation model including flow-electric-temperature-structure field were established to analyze the corrosion process of the anode material and the change trend of temperature,hydrogen volume fraction, electrolyte conductivity and current density in the processing gap.The analysis results show that the temperature and hydrogen content gradually increase along the process direction.The current density and material removal showed a parabolic trend of the upper opening and the lower opening, respectively.The simulation of the different physical field changes in the electrochemical machining blade profile can not only better understand the complex physical phenomena in the machining, but also provide a theoretical basis for the selection of actual electrochemical machining parameters.

电化学加工瞬态过程的多物理数值模拟
为了充分了解电化学加工过程,建立了包括流电温度结构场在内的多物理耦合模拟模型,分析了阳极材料的腐蚀过程以及加工间隙中温度、氢体积分数、电解质电导率和电流密度的变化趋势。分析结果表明,温度和氢含量沿工艺方向逐渐增加。电流密度和材料去除分别显示出上开口和下开口的抛物线趋势。模拟电化学加工叶片轮廓中不同物理场的变化,不仅可以更好地理解加工中复杂的物理现象,还可以为实际电化学加工参数的选择提供理论依据。
