The invention discloses a rail transit brake disc shape correction analysis method and device, and relates to the technical field of rail transit vehicles and braking of the rail transit vehicles. The method comprises the following steps: performing heat-engine coupling finite element analysis, simulated disassembly and simulated shape correction based on finite element statics analysis on a three-dimensional model of the rail transit brake disc to obtain a buckling deformation amount and shape correction process parameters of the brake disc, and performing data fitting analysis on the shape correction process parameters and the buckling deformation amount to obtain a shape correction result. And obtaining relational data of the shape righting process parameters and the buckling deformation amount of the brake disc, and determining the shape righting process parameters of the disassembled rail transit brake disc according to the relational data of the shape righting process parameters and the buckling deforma
