Abstract
Human body suffers when exposed to different vibration conditions that generated by traveling, working with machines etc. in sitting and standing posture both. In this study, modal analysis has been performed on 54 kg Indian human subject to find out the natural frequency and deformations for both sitting and standing posture under un-damped vibration conditions. An ellipsoidal approach has been used to model human subject as 3-D CAD model using physical dimensions and anthropometric data available in existing literature. Human subject is divided into different segments to convert complex human body into simple model using ellipsoidal shape of each segment. The results obtained in this study, will be helpful in designing components for human use like automobile seats, lifts, escalators, machine parts, etc. Also, in this study a comparison has been done in the results obtained in sitting and standing posture analysis. Further, it was found that with the increase in natural frequency, deformation increases in both the cases.
