| 摘 要： | 将静电感应给电方法应用于大面积电火花成形加工,并对极间充电特性进行了仿真及实验研究。结果表明:在极间加工面积较大的情况下,当极间距离小于某一数值后,极间开路电压随着极间距离的减小而降低;给电电容越小,极间开路电压随极间距离的变化越明显;当极间距离一定时,极间开路电压随着给电电容的增大而升高。

| Abstract: | The electrostatic induction feeding method was applied to the large area sinking electro-discharge machining (SEDM),and theoretical analysis and experimental investigation were conducted to clarify the charging characteristics of the working gap. The results showed that when the work surface area is larger,after the working gap distance falling to some value,the charged open voltage of working gap decreases with decreasing the gap distance. The smaller feeding capacitance is ,the more obvious the charged open voltage of working gap varies with the gap distance. Besides ,the gap open voltage increases with increasing feeding capacitance under a certain distance gap. |
