Abstract [en]

Marine vessels are known to undergo various types of loading when traversing water, one of which are the g-forces caused by crashing into waves. These g-forces can cause the rubberized mounts that support the engine to bottom out and can also impact the bending moment experienced by the flanges at the junctions between components.

The goal of this work was to create a program using a generalized analytical model to run a static analysis on any particular combination of components and yield data such at the point at which a mount bottoms out and the bending moments at the flanges between components. This model was then compared against a finite element model to evaluate its usefulness.

It was concluded that while for most of the cases, the simplified analytical model yielded acceptable results, the deviances caused by particular cases deem the model to not be robust enough to be trustworthy, and as such the model would require further work to be useful.
