灯光罩网远洋渔船波浪载荷分析
|
摘要
针对灯光罩网渔船,考虑其作业时的危险工况,采用基于三维势流理论的COMPASS WALCS-Basic软件进行波浪载荷短期预报,给出了危险工况下的波浪载荷及其引起的应力响应,并与规范中的名义波浪弯矩及其相应的应力计算结果进行了对比分析,确定渔船在危险工况下结构满足安全要求.
Considering the effect of struts and lead hammers on the hull of a fishing vessel with Lighting Cover,a software COMPASS WALCS-Basic based on three-dimensional potential flow theory is used to predict the short-term wave loads.The wave loads and stress responses under dangerous conditions are analyzed and compared with the nominal wave bending moments and corresponding stress calculation results in the code. It is determined that the structure of the fishing vessel meets the safety requirements under dangerous conditions.
