摘要
分析了超大型油船在主机激励下的振动响应,并进行了相应评估。主机工作过程中产生的激励力是引发船舶振动的主要原因之一。本文基于全船三维有限元模型,分析了主机H型倾覆力矩、X型倾复力矩、四阶垂向力矩和二阶垂向力矩对船体振动的影响。通过频响分析,得到了驾驶室在主机激励下的振动响应,并依据相关衡准条件,对振动情况进行了评估。
The influence of main engine on vibration response of very large crude oil carrier is analyzed and evaluated. Excitation force due to main engine is one of the main reasons for ship vibration. According to three dimensional finite element modeling of whole ship, analyze the influence of main engine excitation(H overturning moment, X overturning moment, 4th vertical moment and 2th vertical moment) on ship vibration. According to frequency analysis, obtain vibration response of steering room due to engine excitation. Evaluate vibration situation due to the related criterion conditions.
