Abstract

Entire body vibration causes a multifaceted sharing out of vibration within the body and disagreeable feelings giving rise to discomfort or exasperation result in impaired performance and health menace. The current study proposed a 4-DOF analytic biomechanical model of the human body in a sitting posture without backrest in vertical vibration direction to investigate the biodynamic responses of different masses & stiffness and Analysis by using Response Surface Method. Response surface methodology (RSM) is a collection of mathematical and statistical technique useful for analysing problems in which several independent variables influence a dependent variable or response and the goal is to optimize the response. The experimental set up will be design to get the entire speed range with the mass damper system. The mass damper system model will be formulated for the sitting posture like Auto Rickshaw human sitting posture. The biodynamic response characteristics of seated human subjects have been extensively reported in terms of apparent mass and drivingpoint mechanical impedance while seat-to-head vibration transmissibility has been widely used to characterize response behaviour of the seated subjects exposed to vibration. This Work helps to improve sitting comfort of commercial vehicle at various speed ranges and also improves Human work capability.
