Multiphysics Numerical Simulation of High Frequency Short Pulse Electrochemical Machining for a Engine Blade

与传统直流电解加工相比,高频窄脉冲电流电解加工在复制精度、重复精度、表面质量、加工效率、加工过程的稳定性等方面均有显著提高,特别适用于要求高精度和高表面质量的具有复杂几何轮廓零件的精密加工。文中在建立叶片电解加工区域二维模型的基础上,分别进行了直流电解加工和高频窄脉冲电流电解加工的电场与流场的耦合数值模拟,对比结果验证了高频窄脉冲电流电解加工较传统直流电解加工的优越性。

Compared with traditional DC electrochemical machining, High Frequency Short Pulses Electrochemical Machining（HSPECM） has more increase significantly in terms of replication accuracy, repeatability precision, surface quality, working efficiency and the stability of machining process. Based on establishing a two-dimensional geometry model of the electrochemical machining field for a blade, the multiphysics numerical simulations of DC electrolytic machining and high frequency short pulse electrochemical machining are carried out. Comparison results confirm the superiority of high frequency short pulse electrochemical machining over traditional DC electrolytic machining.
