Abstract

Background / Objectives: To find the human response in standing posture while subjected to random vibration conditions at different acceleration conditions. Methods/Statistical Analysis: It is a numerical approach, in which author has done analysis using FEM, and during this study statistical table has used to represent the data in Tabular form with appropriate figures that have used during current study. Findings: Human body suffers from vibration and its ill effects on daily activities. There are many sources of generation of vibrations that effect comfort and health of human i.e. harmonic vibrations, transient vibrations and random vibrations. The tendency to come in contact with random vibrations and its effect is more as compared to other vibration conditions. Improvements/Applications: Taking a special case of random vibrations and standing posture of human body, this study has been performed. The results obtained using this study shows that more stresses are produced in human body when random vibrations have been applied in vertical direction. FEM model of 76 kg male Indian human subject has been modelled using 95th anthropometric data available in literature.
