Effect of ice-load and trim angle on the strength of propeller

  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.
