Abstract：The ice-induced load on a ship hull is a key point in the study field of icebreaker.Based on the full-scale measurement data here,the influence coefficient matrix method and the inverse method were applied to analyze the ice load on the stern shoulder area of the polar supply and research vessel S.A.AgulhasⅡ.The ice loads on different frames were therefore obtained by transforming the shear strain data measured with sensors attached on those frames and using the coefficient matrix in MATLAB.To get the ice load distribution,the finite element model in the stern shoulder area was built and two different discretization methods were used to discrete the load area.Tikhonov regularization was employed to solve the inverse equation,the ice load distribution on the outside plate was gained.The results showed that the two methods proposed can lead to similar solutions and overcome the ill-posed nature of solutions during data processing.
