基于规范-数值-试验手段的大型船舶波浪载荷综合分析
Comprehensive analysis of wave loads on large ships based on rules-numerical-experimental techniques
摘要
Abstract
Aiming at the problem that the high-frequency whipping responses of large ships were prominent in high sea conditions and it was challenging to predict the strongly nonlinear wave loads accurately,a fully nonlinear time-domain hydroelastic numerical method was established,in which the free surface and wetted body surface were updated transiently,and the real navigating state of the ship in waves could be simulated.The results of the numerical method of an ultra large container ship agreed well with the data of segmented model tests in large-amplitude waves.Based on the long-term extreme value at 1× 10-8probability level,the nonlinear equivalent design waves and the corresponding design wave loads in service condition(economical speed)as well as extreme condition(low speed)of the numerical method were determined.By the analysis of the rule,numerical method and model tests,it is found that the current UR S11A standard lacks sufficient safety margin with regard to the selected container ship.In accordance with the above investigations,an effective assessment procedure for the design wave loads on large ships was demonstrated.关键词
