CONCEPT MODELING AND ANALYSIS OF BODY IN WHITE USING BEAM ELEMENTS

In this paper, Concept Modeling and Analysis of Body in White by using Hpermesh software is discussed. The companies first design the concept model of the car by using a CAD software. Altair Hyperworks software is used to create models. Beam and shell elements have been used to design the Body-inwhite structure of the vehicle. The modeling has done by using beam elements for creating the structural frame of the car, the model is imported and solved using MD Nastran. In order to perform the modal analysis of the model SOL 103 is used. The mode shapes and natural resonance frequencies can be visualised using Hyperview software. The frequency response functions of Inphase, Outphase and Single node are detailed. The SOL 111 is used to obtain the Frequency response functions under different conditions. The graphs are visualised using Hypergraph software. Based on the structural integrity the design of structure, alterations are done to it to get satisfactory values which can make the car stiffer. The results obtained confirms to the actual model, which can be compared with any hatchback vehicle.
