In this work, the design and the optimization of an experimental test bench for the experimental characterization of impulsive water-entry problems are presented. Currently, the majority of the experimental apparatus allow impact test only in specific conditions. Our test bench allows for testing of rigid and compliant bodies and allows performing experiments on floating or sinking structures, in free-fall, or under dynamic motion control. The experimental apparatus is characterized by the adoption of accelerometers, encoders, position sensors and, above all, FBG (fiber Bragg grating) sensors that, together with a high speed camera, provide accurate and fast data acquisitions for the dissection of structural deformations and hydrodynamic loadings under a broad set of experimental conditions.

Abstract

In this work, the design and the optimization of an experimental test bench for the experimental characterization of impulsive water-entry problems are presented. Currently, the majority of the experimental apparatus allow impact test only in specific conditions. Our test bench allows for testing of rigid and compliant bodies and allows performing experiments on floating or sinking structures, in free-fall, or under dynamic motion control. The experimental apparatus is characterized by the adoption of accelerometers, encoders, position sensors and, above all, FBG (fiber Bragg grating) sensors that, together with a high speed camera, provide accurate and fast data acquisitions for the dissection of structural deformations and hydrodynamic loadings under a broad set of experimental conditions.
