Ddam Response Spectrum Analysis In Abaqus Pdf Areas Of Computer Abstract and figures this article describes the evolution of the dynamic design analysis method (ddam) by assimilating information from references spanning more than three decades. Ddam is similar in concept to the traditional shock spectrum method, but it is tailored for naval shock response and addresses some of the limitations of the traditional method that show up in ship design situations.
Pdf Dynamic Design Analysis Method Ddam The dynamic design analysis method (ddam) is a us navy developed analytical procedure for evaluating the design of equipment subject to dynamic loading caused by underwater explosions (undex). "".this report describes the theory, implementation, and use of the dynamic design analysis method (ddam) in the nastran finite element structural analysis computer program. ddam is the procedure used in the shock design of shipboard equipment. The dynamic design analysis method (ddam) provides a method for analyzing shipboard components that are subjected to a shock event due to an underwater explosion. Dynamic design analysis method (ddam) effectively predicts naval equipment response to underwater explosions. ddam computes acceleration, velocity, displacement, and stress for naval systems with few degrees of freedom.

Analysis approach in a ddam for abaqus analysis, three primary tasks must be completed. each has its own task manager. This section of the article sketched how the ddam method evolved from difficulties with en velope spectra, fiducial limit spectra, and aver aged spectra to a spectral technique that uses the fixed base natural frequencies and modal effec tive masses as design parameters to account for the equipment structural interaction. The purpose of a dynamic design analysis method (ddam) in fea is to find a system’s response to a shock load without the need for a shock curve (acceleration vs. time graph), using empirical correlations instead. This report describes the theory, implementation, and use of the dynamic design analysis method (ddam) in the nastran finite element structural analysis computer program.
