摘　　要：[目的]在冰区航行对船舶螺旋桨强度的要求很高,因此对不同情况下螺旋桨的强度进行研究十分重要。[方法]基于有限元方法,以Workbench为工具,计算在冰区运行的不同纵倾角螺旋桨不同工况下的应力、应变,并在计算前开展网格收敛性研究。[结果]由分析计算结果可知:冰级越低,螺旋桨桨叶受到的冰载荷就越小,应力、应变也越小;部分工况下螺旋桨的应力、应变变化十分类似;较大的纵倾角对螺旋桨桨叶的应力、应变影响较大。[结论]计算结果可为冰区船舶螺旋桨的强度设计提供参考。[Objectives]Propeller strength is of vital significance for ships sailing in icy regions,so research into the reaction of propellers under different operating conditions is necessary.[Methods]Based on the Finite Element Method(FEM)this paper uses Workbench to calculate the stress and strain of propellers with different trim angles in different operating conditions,developing grid convergence research before calculation.[Results]As a result,the stress and strain value reduces along with the PC;the influence on the stress and strain of the propeller is quite similar in some cases;and larger trim angles have significant influence on the stress and strain of the propeller.[Conclusions]This paper can provide references for propeller strength design.
