The purpose of this paper is to study NVH (Noise Vibration and Harshness) characterization of composite material component use in commercial vehicle by using finite element software. Noise and vibration is considered as an important aspect in development of vehicle. Composite materials are becoming famous in automobile sector as they have high strength, damping and low mass density, although they are relatively costlier. Moreover composite properties can be changed by tuning material composition, fiber orientation angle and layer thickness. Front cage model is evaluated for its modal and dynamic response. Simulation is carried out using 2D PCOMP element of HYPERMEH and NASTRAN. Predicted modal and dynamic responses are validated with experimental results. Composite component shows considerable weight saving with improved performance over sheet metal.
