A floating model based on multi-center force applied to irregular floating objects

Abstract
The swinging posture of floating objects plays an important role in improving the simulation degree of oceanic scenes. In this paper, we study the influence factors of swinging posture of floating objects in oceanic scenes, including the environment and its own influences. For the problem that the traditional floating model only applies to regular objects, such as boxes, we propose a floating model with multi-center force, including the confirmation of the center of the corner block, the distribution of weights, the vector synthesis of forces, and the determination of resistance problems. This model analyzes the shape of floating objects and allocates a branch center of gravity for the more prominent corner blocks, which makes the corner block contribute to the swing posture. In this way, the swing posture of irregular floating objects is more in line with reality. Through experimental comparison, a floating model based on multi-center force shows swinging posture which is more consistent with practical mechanics than the traditional single-center floating model on the irregular floating objects with more corner blocks.
