摘　　要：[目的]为实现双臂艉轴架轻量化设计,[方法]通过对比分析国内现行规范和世界主要船级社关于艉轴架的相关尺寸要求,解读各规范之间的差异,从差异中寻找双臂艉轴架轻量化方法。根据规范之间的差异,选取与中国船级社(CCS)(海船)规范差异较大的挪威船级社—德意志劳氏船级社(DNV-GL)(船舶)规范,针对同一螺旋桨参数,分别根据各自规定的最小尺寸设计双臂艉轴架,采用相关标准规定校核各自的性能。[结果]结果表明,根据两规范进行尺寸设计的艉轴架强度和振动性能均符合要求,而按照DNV-GL(船舶)规范最小尺寸要求设计的艉轴架总质量轻约16.8%。[结论]采用DNV-GL规范设计艉轴架,能在一定程度上实现轻量化,为实际工程中艉轴架的轻量化设计提供思路。[Objectives]To achieve lightweight design of double-arm propeller shaft brackets.[Methods] By comparing and analyzing the requirements of the current domestic rules and the main classification societies in the world for the dimension of propeller shaft brackets,this paper interprets the differences between the rules,and searches for ways to reduce the weight of the double-arm shaft brackets from such differences. According to the differences between the rules,DNV-GL rules with significant differences from the CCS rules in the relevant aspects are selected. Based on the same propeller parameters, double-arm propeller shaft brackets are designed according to the minimum sizes requirements specified in the two rules. Subsequently,the strength and vibration performance of the double-arm propeller shaft brackets are verified by the relevant regulations of the national military standard.[Results]The results show that the strength and vibration performance of the propeller shaft brackets designed according to the two rules meet the requirements. The total weight of the propeller shaft brackets designed according to the minimum sizes requirements of DNV-GL rules is reduced by about 16.8%.[Conclusions] If the double-arm propeller shaft brackets are designed with the DNV-GL rules,the weight thereof can be reduced to some extent. This paper provides an idea for the lightweight design of the double-arm propeller shaft brackets in practical engineering.
