铝合金船体在高速船、特种船舶等船型中有广泛应用，铝合金船体搁浅损伤会对船舶航行安全造成严重影响。提出了一种基于数值分析的铝合金船体搁浅损伤研究方法，阐述了船舶搁浅过程的3个阶段的基本受力情况，建立基于ABAQUS的铝合金船模型，并设置材料参数、接触参数、分析步参数等，最后对船底损伤情况以及不同工况下铝合金船底板受到的水平切割力进行分析。结果表明，通过数值分析可以根据不同搁浅初速度和礁石形状等对船体损伤情况进行判断，以方便快速制定救援方案。
Aluminum alloy hull is widely used in high-speed ships, special ships and other ship types. The grounding damage of aluminum alloy hull will seriously affect the navigation safety of ships. This paper proposes a numerical analysis based research method for the grounding damage of aluminum alloy hull, expounds the basic force conditions of the three stages of the ship grounding process, establishes the aluminum alloy ship model based on ABAQUS, and sets the material parameters, contact parameters, analysis step parameters, etc., and finally analyzes the damage condition of the ship bottom and the horizontal cutting force subjected to the aluminum alloy hull bottom under different working conditions. The results show that the damage condition of the ship can be judged according to the initial speed of grounding and the shape of reef by numerical analysis, so as to make the rescue plan quickly.
