WebA modal analysis and DDAM application were performed to determine the resulting displacements in the different modes of the systems. These displacements were then applied to the system in order to determine whether the combined modal displacements caused the critical component, represented by two thin beams, to make contact. WebDDAM to analyze the shock responses of the large motors. Lee (2 012) performed the shock-resistance response analyses of the ship st eering system using the DDAM. Bae et al. (2009) and Seong et al. (2015 ) applied the BV043 to analyze the shock responses for the propul sion motor. Kim et al. (2024) evaluated the shock-resistance perform ance griffin ghost

Webshock design values N from design curves, such as those shown in Fig. 4. This is essentially the DDAM approach for estimating the maximum deflections and stresses experienced by the equipment using modal analysis. The shock design curves represent a compilation of shock data as described in reference [9].
