Abstract
During daily activities, individuals come into contact with various intensities and durations of vibrations, which can potentially lead to health issues such as headaches, vomiting, and even heart failure. When designing components for human use, it becomes essential to assess the vibration parameters affecting the human body, allowing for necessary actions to minimize its impact. In a current study, a 76 kg mass representing the 95th percentile anthropometric Indian human male population was used and a realistic CAD model was created, incorporating different anatomical layers and defining material properties for various organs and components. To understand the effect of vibrations, modal analysis was conducted on the standing posture of the human subject. This analysis helped identify the natural frequencies (eigenvalues) and the vibration patterns (mode shapes) as well as the deformations experienced by each anatomical layer. Notably, the head and lower arms were found to experience the maximum effects of vibration across all types of anatomy layers. The natural frequency values obtained in this study were compared with experimentally obtained data available in existing literature for further validation.
