The ice load caused by the contact between the propeller and the sea-ice with different physical parameters will have different influences on the propeller and propulsion shafting. The study of the influence of the ice load on the shafting and the response of the shafting can provide suggestions for the design and arrangement of the propulsion shafting.The ice load on the propeller caused by the contact between the propeller and different physical parameters is calculated by using ANSYS/LS-DYNA based on the fluid structure interaction method, and then the variation of the ice load is analyzed. The obtained ice load is input into ABQUAS to calculate and analyze the stress and strain of the propulsion shafting under the corresponding ice load in order to get the response of the propulsion shafting. It shows that the dynamic response of the propulsion shafting is greatly affected by the ice load, which increases with the decrease of the radial distance of the sea-ice and the increase of the size and velocity of the sea-ice. Higher strength requirements are therefore demanded for the propulsion devices of ice ships.
