In this study, a CAD model of Indian male human subject of mass 54 kg and 76 kg has been generated using ellipsoidal and solid model approach. A modal analysis has been performed using FEM on these CAD models to calculate natural frequencies and mode shapes at different natural frequencies. An effect of vibrations of different amplitude and frequencies have been calculated using harmonic response analysis under different damping conditions. The purpose of this study is to find out the natural frequencies and corresponding mode shapes which may be helpful in avoiding resonance that are beneficial in designing products for the day to day life of human use such as lifts, escalators, hand rails etc.
