description The invention relates to a method for designing an equal-thickness scaling fatigue test model, which is used for carrying out equal-thickness scaling design on a structure after a typical high-stressnode of the structure is selected, and comprises the following steps of: step 1, selecting the typical high-stress node of the structure as a fatigue test node according to a finite element analysis result; step 2, according to the selected node cross section width B and height H, considering the maximum loading section size S1 * S2 of a loading device, and determining a model cross section scaleratio by utilizing the following formula: representing rounding upwards, and taking the large value in a1 and a2 as the model cross section scale ratio 1: ai, i = 1, 2; and keeping the rib distance ofeach node unchanged; and step 3, selecting the shell plate thickness of each part of a fatigue model according to the real shell plate thickness of the structure, wherein the welding process of the node adopts the same welding
