拖带船队撞击钢围堰防撞墩的数值模拟分析

拖带船队是京杭运河中的重要船型之一,运河中船桥相撞击事故时有发生.为了探讨拖带船队对运河桥梁桥墩的撞击作用,以便更好地设计运河桥墩的防撞设施,该文利用ANSYS/LS-DYNA软件建立了拖带船队和钢围堰填土防撞墩的有限元计算模型,模拟计算了拖船与防撞墩之间的撞击作用,得到了撞击力和撞击能量时间历程的合理规律,可供运河桥墩的防撞设施设计参考.

Numerical Simulation for the Towing Fleet Impact on Anti-collision Pier of Steel Cofferdam

Towing fleet are one of the main ship types in the the Grand Canal,where collision accidents between ships and canal bridges often occur.For discussing the role of pulling mule-fleet impact on the canal bridge pier and in order to better design the anti-collision facilities of the canal bridge piers,finite element models of pulling mule-fleet and anti-collision pier of steel cofferdam was set up based on ANSYS/LS-DYNA Software.The simulate calculation of impact effect between pulling mule-fleet and anti-col...
