전극봉의 와이어 체결 유무에 따른 자유 벌징 금형의 액중방전성형 실험을 통한 SUS430 소재의 성형성 비교 = Experimental Comparison of Electrohydraulic Forming of SUS430 with Free Bulging Die Depending on Wire of Electrodes

다국어 초록 (Multilingual Abstract)

Electrohydraulic forming(EHF), one of the high-speed forming method, can supplement the weak point of previous forming process such as deep-drawing and electromagnetic forming. Indeed, EHF is time-consuming process during installing wire before experiment that hard to apply to industry. In this research, applying wireless electrode, the formability of SUS430 sheet was compared through EHF experiments using wire-installed electrode and the other, wireless. Although the power was a little lacking, the advantages of the experiment using wireless electrode could be confirmed with checking the optimal location of electrodes where the plasma is generated and comparing free-bulging height depending on former and later condition of electrodes with performing several single and multistage experiments for same voltage, 6 kV.
