PURPOSE: A method for analyzing a dynamic load of shafting is provided to directly measure a dynamic load generated from propeller of a real ship, thereby securing bearing stability of the shafting connected to the propeller in a designing step. CONSTITUTION: A first shafting amount of deformation is measured. A second shafting amount of deformation is measured. The amount of change of shafting deformation is calculated in each joint of shafting caused by a dynamic load based on the first shafting amount of deformation and the second shafting amount of deformation. A stiffness matrix of the shafting and the stiffness matrix of a hull in each bearing position of the shafting are obtained. A sum matrix which the obtained shafting stiffness matrix and the obtained hull stiffness matrix are summed is calculated.
