Abstract
The characteristics of a dual-pulse shock caused by an UNDEX (underwater explosion) are described through many standards. Shock signals required to evaluate the survivability of equipment by a shock test machine are also described. To generate various types of shock signals described in the standard, Shock test machines (STMs) require adjustment to various levels of shock occurring in surface ships and submarines. Therefore, the characteristics of each component of a STM should be changeable to generate various shock signals. This paper describes the concept of a STM that can generate various types of dual-pulse shocks. Moreover, this paper suggests an analytic method to determine the characteristics of each component of a STM to generate the required shock signal for various specimens. A method for adjusting the shock signals using a magnetorheological damper is specifically suggested. The results of dynamic analysis using the characteristic values of each component determined by this method shows that the required shock signal can be generated by this concept of the shock test machine.
