A Correct Smoothed Particle Method to Model Structure-Ice Interaction

摘要

This paper studies the effect of ice resistance on the icebreaking capacity and speed of an icebreaking vessel. We combine an improved Correct Smoothed Particle Method (CSPM) with a material low-speed collision fracture model to numerically simulate the continuous icebreaking and rolling process of crushed. Using this model, we investigate the icebreaking resistance and immersion resistance during the icebreaking process, taking into account the fluid (water) as the elastic boundary support and the fluid-solid coupling interaction. We compare the icebreaking resistance and broken ice fracture shapes obtained by the numerical calculation with the theoretical analytical results, and thus validate the improved CSPM method. Further, we compare the immersion resistance results from our simulation against that from Puntigliano [Puntigliano, Hamburgische Schiffbau-Versuchsanstalt GmbH (1995)], and demonstrate that the proposed method can accurately predict ice resistance.
