Abstract

The proposed activity aims to investigate global and local hydrodynamic loads as well as elastic responses of X-Craft catamaran in rough sea and to enhance understanding of correlation between applied loads and induced responses. The project focus on an innovative design of the elastic model which scales the hydrodynamic and structural ship behavior. The elastically scaled model is then aimed to provide a complete picture of the inflow conditions, loads and responses through extensive and high-quality data to be used for comparison with numerical predictions. In particular, the evaluation of hydroelastic coupling relative to wet-deck panels (metallic and composite) will be addressed with detailed experimental and numerical analyses and is regarded as a first step for future developing of slamming alleviation techniques.

Goals

1. Performing an experimental campaign with an elastically scaled model of the Sea-Fighter catamaran devoted to collect data for the analysis of critical load and response phenomena as well as for the validation of numerical codes. In particular, modal parameters of the elastic model will be identified and the unsteady, continuous load field will be reconstructed on theg basis of available data.
2. Improving the knowledge of global hydrodynamic loads and elastic responses at model scale in wavy seas with particular reference to the relationship between slamming load and induced response.
3. Evaluating the hydroelastic effect on deck metallic and composite panels as a first step toward slamming mitigation via their proper design.
4. Establishing the correlation between model-scale and full-scale measurements accounting for scaling effects and other simplifying hypotheses that need to be set for the physical model construction. Critical points in the correlation and possible source of mismatch in data comparison will be pointed out.
