In setting an analysis condition of optimization analysis (21), an optimization analysis device for a load transfer structure in a body frame part of an automobile according to the present invention sets an impact load input portion 121 and a plurality of load transferred portions 123 in the body frame part of an optimization analysis model 120 (21a), divides a crashworthiness load into loads having loading capacities equal to or smaller than loading capacities of the plurality of load bearing members and determines transferred loads at the load transferred portions (21b), sets a loading condition defined to set the determined transferred loads as pieces of reaction force of the crashworthiness load for the load transferred portions 123 and a constraint condition defined to constrain displacement of the impact load input portion 121 (21c), and sets, as an optimization analysis condition, a predetermined objective and a constraint that displacements of the plurality of load transferred portions 123 are equal (21d).
