Abstract

The establishment of a finite element model that conforms to the actual assembly structure is the key to the dynamic optimization design of the structure. To this end, a three-dimensional CAD model of the white body of the Iveco A40 new passenger car has been established and the conversion to the finite element model has been achieved. Through the modal test of the white body, and the finite element model was modified to match the results of the finite element analysis with experimental test results. A finite element model that can reflect the dynamic characteristics of the actual body structure was obtained, laying the foundation for the structural optimization design of subsequent bodywork.
