AbstractThe roll motion response of a single degree freedom (SDOF) structural system to which rigid rectangular partially filled liquid tank has been attached is considered. The SDOF with the empty first described mathematical model and this validated by performing decay experiments as well in periodic excitations are applied system. responses accurately predicted model. accuracy these predictions allows us study both experimentally numerically, weakly compressible SPH, performance tuned...
In this work a combined analytical-numerical approach is proposed to address the problem of ship roll motion under action wind and waves. Roll modelled as one-degree-of-freedom system non-linear in both damping restoring. The modular, allowing an easy update methodology on basis new research outcomes. Realistic environmental conditions regarding effects waves are taken into account can be easily changed. spatial correlation gusts by means ‘aerodynamic admittance’ function, whereas moment due...
This paper addresses, starting from an extensive series of tests in longitudinal regular waves (already done) and irregular (in progress), the problems connected with threshold formulation for parametric rolling its amplitude modeling above threshold. Both head following have been considered, also view greater attention to sea conditions called during International Maritime Organisation Subcommittee on Stability Load Lines, Fishing Vessels Safety (IMO/ SLF) discussion revision Intact Code....
The present paper focuses on the analysis of impact pressure registrations from repeated model scale sloshing experiments under harmonic rotational excitation. A series more than 100 experiments, each one encompassing events, has been conducted seeking highest feasible repeatability. Different excitation periods, that cover main features dynamics, have considered in a preliminary screening, describing dynamics. Since, even nominally deterministic excitation, at is characterized by high...
