大水位差框架墩式码头动力仿真分析

Dynamic simulation for frame-pier in river with large fluctuation

结合三峡库区某框架墩式码头工程,通过有限元动力仿真方法,利用非线性分析软件ANSYS/LS-DYNA建立了船舶与独立墩式码头碰撞的有限元模型,模型中考虑了橡胶护弦的缓冲和吸能作用,更加真实地模拟出船-护弦-码头三者之间的相互作用。模型分析了船舶速度对墩式结构动力响应的影响。

Based on the case of Naxigou port in Three Gorge reservoir, taking advantages of the finite-dynamic simulation method, we establish the collision model between ship and flame-pier wharf by non-linear analysis software ANSYS/LS-DYNA. In order to simulate the interaction among the ship, the frame-pier wharf and the rubber fender more accurately, we take the cushioning effect and energy absorption of rubber fender into consideration in this model. The influence of various factors are also analyzed.
