Natural Frequency Analysis of Automobile Seat

paper, analysis of automobile seat for natural frequency is presented. The IGES model of automobile seat is analyzed on HyperMesh and post processing is done by using NASTRAN solver. All the pre-processing steps are described in details. In pre-processing automobile seat components are meshed with quads and tria elements and solid components are meshed with hex element. Analysis is conducted for free vibration by considering each component separately. Only a fundamental natural frequency is considered in the analysis of critical components. Keywordsnatural frequency, finite element analysis, free vibration.
