摘　　要：为了缩短阳极喷嘴研制周期,按液体湍流建立加工区域流场的数学模型,并按照"电镀,移动网格"建立二次电镀的数学模型,根据电喷镀加工工艺参数设置边界条件,采用COMSOL Multiphysics软件对加工区域进行数值模拟,分析加工区域流场分布及电场分布对实际加工的影响,并模拟不同时刻阴极生长的轮廓曲线,最终确定较好的阳极喷嘴设计方案。结果表明,底端圆弧状的阳极喷嘴获得的沉积层效果较好,计算机模拟结果与工艺试验结果一致。In order to shorten the preparation period of anode nozzle, a mathematical model ol the liquid field in machining area was built according to liquid turbulent flow, and a mathematical model of secondary electrodeposition was built according to electrodeposition with moving geometry. The boundary conditions were chosen according to the parameters of the jet-electrodeposition experiments. Software, COMSOL Multiphysics was used to simulate the machining area. The influences of liquid field and electric field distribution on machining precision were analyzed, and the profile curves of eatb.ode grovcth at different times were simulated. And then the nice solution of anode nozzle was de- termined. It is demonstrated that the bottom of an arc-shaped anode nozzle will be the better to ma- chining. The simulation results are in a^reement with that of the experiments.
