납 콘 충격 프로그래머를 이용한 ER-MLRS의 톱니파형 구현

Lead is used as the material of the specific structure to perform saw-tooth wave shape. As using the low elastic modulus and deformation of the lead, the various saw-tooth wave shapes of the impactor were obtained. The specific structure is called “lead cone shock programmer”. In this paper, the design and simulation of the lead shock programmer is performed to generate saw-tooth wave shape to meet requirements of ER-MLRS. Results of the time history was compared with ideal saw-tooth wave shape and simulation. As using tolerance range of the saw-tooth shock wave presented in MIL-STD-810G, handed ER-MLRS saw-tooth shock wave was in tolerance range.
