기하 형상비에 따른 납 충격 프로그래머의 가속도 주기 특성에 관한 연구

다국어 초록 (Multilingual Abstract)

In this study, the lead shock programmer with truncated shape was studied. As the low elastic modulus of the lead, various acceleration periodic characteristics of the test bed were changed. The bottom diameter and height of the conical shock programmer was design parameter of the shock programmer. The above diameter, bottom diameter and height of the lead shock programmer with truncated shape were design parameters of the shock programmer. The velocity of the impactor was 3 m/s. The aspect ratio of the conical shock programmer was applied height over the bottom diameter (h1/D1) of the shock programmer. Two type of the truncated shock programmer was applied that one was height over the bottom diameter (h2/Dbot) of the shock programmer and the top diameter over the bottom diameter (Dtop/Dbot) of the shock programmer. The range of all aspect ratios in this paper was applied 0.2 to 5. The time history on the acceleration of the test bed by simulation was compared under various parameters
