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。
運用LS-DYNA對船橋撞擊進行倣真模擬,證實瞭船舶剛度與船橋撞擊力為一次線性關繫。噹該線性關繫斜率為0.5時,船舶的剛度會對船橋撞擊力產生重大影響,因此在船橋撞擊的實用計算公式噹中,應攷慮船舶的剛度因素。
운용LS-DYNA대선교당격진행방진모의,증실료선박강도여선교당격력위일차선성관계。당해선성관계사솔위0.5시,선박적강도회대선교당격력산생중대영향,인차재선교당격적실용계산공식당중,응고필선박적강도인소。
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.
