用LS-DYNA仿真模拟探索船舶刚度对船桥撞击力的影响

摘要

运用LS-DYNA对船桥撞击进行仿真模拟，证实了船舶刚度与船桥撞击力为一次线性关系。当该线性关系斜率为0．5时，船舶的刚度会对船桥撞击力产生重大影响，因此在船桥撞击的实用计算公式当中，应考虑船舶的刚度因素。%Whereas there is defect of standard formula in vessel-pier crash, LS-DYNA is employed to simulate the vessel- pier crash and the result indicates that impact force in vessel-pier crash has primary linear relation with ship stiffness. Providing the linear relationship slope is 0. 5, the ship stiffness can have a massive impact on vessel-pier crash, therefore, ship stiffness shall be taken into account in the pragmatic calculation for vessel-pier crash.
