摘要
针对回转式起重船作业时受船舶通航影响的问题,以船行波理论分析船行波波高及波高衰减,依据船舶原理分析起重船作业稳性,按照规范要求的最大作业横倾角推算起重船所能承受的最大波浪扰动力矩,进而得出船舶通航时的合理航速及距离,算例表明起重船吊臂旋转90°作业时受波浪扰动影响较明显,同时通航船舶航速与安全距离存在相互影响。
Aiming at the problem of that the operation of crane vessel in construction water area is affected by ship navigation,the theory of ship wave was applied to study wave height,wave height attenuate and operational stability of the crane vessel.The allowable wave disturbing moment of crane vessel was reckoned according to the maximum heeling angle assigned by rules,so as to calculate the reasonable speed and distance for navigation ship.A numerical case showed that when the boom rotates 90°,the influence of wave disturbance is most obvious,meanwhile there is interaction between speed and distance of navigation ship.
