Hydro impact and fluid structure interaction of a racing yacht
Hydro impact and fluid structure interaction of a racing yacht
The hydro impact caused by slamming on sailing yachts and the local structure's response is studied experimentally and numerically. Pressure transducers and a special measurement system called Slam patch has been designed and implemented to measure the hydro-impact pressure and/or local structure's response. The measurement systems are installed on a 1/7-scaled model of an Open 60 yacht. Modal, rotational drop and seakeeping -slamming tests are carried out. The measured hydro-impact pressue is processed statistcally. A methodology to scale up the test result to prototype is mentioned. At the same time, the trasnient response of a simple clamped beam under half sine impluse is calcualted using a commerical FEM program to study the effect of the realtivity between impulse duration and natural frequency of the beam.

Abstract
The hydro impact caused by slamming on sailing yachts and the local structure's response is studied experimentally and numerically. Pressure transducers and a special measurement system called Slam patch has been designed and implemented to measure the hydro-impact pressure and/or local structure's response. The measurement systems are installed on a 1/7-scaled model of an Open 60 yacht. Modal, rotational drop and seakeeping -slamming tests are carried out. The measured hydro-impact pressue is processed statistcally. A methodology to scale up the test result to prototype is mentioned. At the same time, the trasnient response of a simple clamped beam under half sine impluse is calcualted using a commerical FEM program to study the effect of the realtivity between impulse duration and natural frequency of the beam.
