Summary on Grant Application Form |
|
(1) To formulate a new mathematical technique and to develop a numerical tool based on this formulation in the time domain for predicting large amplitude motions and resulting global and local structural response including slamming response of a fast multihull vehicle advancing in waves. (2) To carry out small scale experiments in the towing/wave tank, and large scale drop tests. The study will begin by deriving a new mathematical model which permits the representation of the responses of a body in six degrees of freedom to arbitrary forcing functions with excitation in all six modes. The three dimensional potential flow and initial value problems will be formulated in which non linear free surface and exact body boundary conditions are satisfied. The wave field will be represented as a train of irregular waves in the time domain which will be generated from a given sea spectrum. The body of the vessel will be represented by a Rankine source distribution over the submerged portion of its surface. The structural response of two large scale models representing the forward part of a fast multihull vessel will be tested. The results of both small and large scale tests will provide physical insight for the development of the proposed prediction methods. The experimental measurements will also be used to validate the numerical tools. The theoretical structural response to slamming will include underwater impact dynamics. This is particularly important for dynamically responsive structures made of light alloys and FRP composites.
