摘　　要：电解加工工件成形过程仿真与监控是电解加工领域的研究热点。以发动机叶片为研究对象,在研究电解加工成形规律的基础上,主要分析间隙内电场的分布,和电解液流场因素的影响,对叶片的电解加工成形过程和最终型面进行了较精确地分析。通过对某型发动机叶片三维复杂曲面的预测分析和工艺实验结果进行的比较和分析,证明了该预测模型具有较高的精度。The shaping process simulation and final shape prediction are important issues in Electrochemical Machining（ECM）. Taking a blade for example,based on the ECM shaping theories,the model for simulating and predicting blade’s shape during the ECM is studied. The finite element method is applied to analysis the electric field distribution in the machining gap under the stationary state of ECM. And the fluid parameters’efforts are also taken into account. It experiments of machining blades are conducted and the results of calculation and experiments show that the model determining anode workpiece shape is of high precision.
