DYNAMIC DESIGN ANALYSIS METHOD AS A PREDICTION OF SYSTEM FAILURES
18Dec_Gottfried_Brian.pdf (1.581Mb)Abstract
The ANSYS Mechanical program was used to model a simple structure representing shipboard equipment. A 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. If so, the system will have a predicted failure. The results were then compared to a NASTRAN time-dependent model for a solution comparison.
