ABSTRACT

This paper focuses on an innovative modeling approach of a floating body undergoing 6 Degrees of Freedom (DoF) motion in a wave current.

This approach is based on finite particles, which provide similar properties as finite elements in classical structure mechanics. It is implemented into a computationally efficient numerical multi-body simulation program, which is flexible in geometry and dynamic load spectrum. It features a particle-based liquid model and provides time accurate hydrodynamic pressure results in three dimensions and 6 DoF. Based on the results of dam break tests and sloshing analysis of specific tank geometries, unsteady impact loads are computed for a floating body. The stresses and strains will be discussed in subsequent volumes of this study in order to optimize the structure in terms of impact pressure loading in wave currents.

Thereby, the floating body geometry is flexible in terms of wall friction, elasticity laws and damping coefficients.

A special focus is set on the wave impact characteristics and the resulting acceleration of the generic body geometry due to the hydrodynamic forces.
