The Modal Analysis for the Separate Frame Construction of a SUV
The market share for sport utility vehicles is becoming increasingly very fast in recent years. Many auto companies are stepping up the work of research and development the new model of SUV. A new SUV body modal is studied in this paper. The finite element model of the SUV frame is built by the HyperMesh and the SUV frame modal is researched by the Nastran. Low-order vibration mode and the first bending and torsion modal strain energy distribution of the SUV body structure are obtained, and the SUV body structure of the dynamic performance was assessed in this paper.
