Description/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.
