| Abstract: |
| The work aims to sort out the research methods of ice load during ship ice interaction and make a review from three aspects:theoretical analysis, experimental methods, and simulation. Firstly, the principle and applicability of direct calculation method and probability method in theoretical analysis were expounded, and the application of direct calculation method in global ice load and local ice load was emphasized. Secondly, the research achievements and progress of laboratory model test and real scale measurement were introduced, and the difficulties in sea ice preparation and equipment environment of the test method were pointed out. Then, the finite element method and discrete element method were compared and analyzed, and the advantages and disadvantages and application range of each method were described. The finite element method had certain advantages in analyzing the process of structural failure and fracture, but the simulation of the ice breaking process was inferior to the discrete element method. Finally, the development trend and existing problems of ice load research methods during ship ice interaction were discussed and summarized, which could provide some references for scholars in the field. |
