摘　　要：针对金枪鱼围网渔船的实际作业工况,采用有限元方法分析了主桅及其附近甲板结构的强度,并依据CCS规范进行强度校核.结合分析结果,提出改进和优化措施,为主桅及其附近甲板结构设计提供了参考.分析表明,主桅及其附近甲板结构整体上满足强度要求;优化后的主桅结构可减重约1.2t,有助于提高整船的稳性。For the actual operating conditions of tuna seiner, the finite element method is proposed to analyze the strength of mainmast and the surrounding decks. The strength of mainmast and the surrounding decks are also calibrated according to CCS rules. Based on the results, several measures are suggested to optimize the structure of mainmast, and the conclusions could be used for references to the structural design of mainmast and the surrounding decks. It shows that the strength of mainmast and the surrounding decks are basically meeting the requirements. After optimizing, the weight of mainmast could reduce about 1.2 tons, which is useful for improving the stability of the seiner.
