The present invention relates to a method for generating an in-cabinet response spectrum. The method comprises: a first step for enabling an operation unit to operate a target layer response spectrum of a corresponding cabinet, and generating an artificial earthquake corresponding to the layer response spectrum by interlocking a program; a second step for inputting the shape and size of the cabinet and the weight of internal devices through an input unit, and enabling the operation unit to perform idealization by a lumped mass numerical model after dividing the cabinet into a plurality of nodes according to the height; a third step for performing an impact hammer test through an impact tester with respect to each node of the lumped mass numerical model computed in the second step, inputting the result value through the input unit, and operating the result value through the operation unit to estimate a dynamic state equation model; a fourth step for inputting an artificial earthquake value generated in the first step through the input unit, and applying the input artificial earthquake value to the dynamic state equation model of the third step through the operation unit so as to obtain in-cabinet response; and a fifth step for enabling the operation unit to convert the in-cabinet response, obtained in the fourth step, into an in-cabinet response spectrum and performing verification.
