MODAL ANALYSIS OF AN AUTOMOTIVE SUB-SYSTEM USING CAE TECHNIQUES

Computer Aided Engineering (CAE) plays an extreme importance in Automotive design. In new product design process, modal analysis plays a major role to find the structural modes and natural frequencies during Finite Element Analyses (FEA) simulations. This work deals with the modal analysis of automotive Cross-Car Beam (CCB) sub-system to find the structural modes and natural frequencies. In this procedure CAD modelling is generated by using Creo 2.0 and Finite Element(FE) Simulation Analysis is carried out via HyperWorks 13.0 and LS-DYNA. The main objective of this work is to optimize the Cross-Car Beam (CCB) Sub-System design before production with the maximum crashworthy concert as per the legal regulations.
