The invention discloses a passenger car multi-material car body bonding and riveting composite steel skeleton structure analysis method. The method comprises the steps that 1, an area needing glue spreading and epoxy resin-based carbon fiber reinforced composite material spreading is cut out of a to-be-bonded-riveted composite structure steel skeleton structure on a vehicle body, and an area withthe half unit size is cut out of the outer side of each junction of the area; Step 2, dividing unit positions on the vehicle body; Step 3, stretching and bonding the composite structure steel skeletonstructure, marking the positions divided in the step 2, respectively stretching the areas where the glue is laid and the epoxy resin-based carbon fiber reinforced composite material is laid, markingthe positions divided in the step 2, and comparing the positions marked twice; Step 4, determining attributes and failure criteria of the glue spreading layer, the rivet, the epoxy resin-based carbonfiber reinforced composite material spreading layer and the steel skeleton material; And 5, carrying out load test and comparative analysis on the steel skeleton structure of the adhesive-riveting composite structure.
