摘要
文章利用数值仿真及模型试验两种方法对船体舷侧板架与冰体碰撞进行研究。首先建立了舷侧板架的缩尺比有限元模型,计算冰体碰撞载荷作用下板架结构响应;进而制作了与有限元仿真相同的舷侧板架模型,进行冰体碰撞模型试验,分别获得冰体对板架结构的碰撞力、板架应力分布、板架变形等结果,最后将试验结果与数值仿真结果进行了比较,两者基本吻合。研究结果揭示了冰载荷作用下船体板架结构的响应规律。
Both numerical simulation and model test method were carried out to research the collision be-tween side grillage and icebergs. The finite element model of side grillage considering scale factor was built, the response of grillage structure under ice load was calculated; and then the same entity of side grillage as the finite element model was made, iceberg collision test was conducted, the results such as impact force, strain and deformation of grillage model were obatined respectively, Finally, The results of model test and numerical simulation are compared, the two agreed basicly. The response law of grillage structure under ice load is revealed by research results.
