The invention discloses an ice region ship propeller blade optimization method for improving ice load resistance. The method is characterized in that the size and range of an ice load on a propeller are simulated through a finite element method, the stress distribution condition is calculated, the ultimate strength and fatigue strength analysis is carried out, the blade design scheme is iteratively corrected, and the ice load resistance of blades is improved on the premise of avoiding design redundancy and ensuring the hydrodynamic performance of the propeller. Compared with the prior art, the method has the advantages of short development period, controllable technical risk under manpower and material resource investment, and important help for improving the design quality and navigation safety of a ship in an ice region.
