摘要
以海上风机吊装作业船为对象,采用MSC.PATRAN软件建立全船结构有限元模型;通过该船的运输、安装等不同作业状况的分析,确定典型计算工况,并进行典型工况下的载荷分析和计算工作;对该船在典型工况下的应力进行计算和分析,得到了全船详细应力分布、变形情况。计算结果可以为海上风机吊装作业船的整体强度评估、船体结构优化提供有效依据,对该类型船的设计开发也具有指导意义。
This paper establishes the finite element model of offshore wind turbine installation vessel with the Software MSC.PATRAN.By analyzing different operation conditions of transportation and installation,the typical calculation condition is determined,the loads and stress wherein are analyzed and calculated to get the stress distribution and the deformation.The results are helpful for structure evaluation and structural optimization,as well as the design and development of OWTI vessel.
