Ergonomic study to compare digital human modeling simulation versus real life and momentum

Abstract

As part of Vehicle Company ongoing efforts to provide employees a safe and healthy workplace. This study investigated how well ergonomics risk assessments on simulations with digital human models match (DHM) the real-life assessments obtaining on a car assembly line. The purpose is validated physical results comparing to virtual analysis of open hood operation. First off all the method used was measure the computer-aided design at virtual analysis to determine the open hood angle, hinge type, distance between hinge and point of force application, hood center of mass and part weight were collected with a Design Engineer. It was established three different angles to calculate three momentums to compare with a real-life and strength capabilities at DHM. This document concluded the validate results at virtual analysis to real life which means an anticipated force value to open hood operation and the force calculated at virtual analysis.
