Integration of Virtual Reality and Digital Human Model Simulations for Ergonomic Analysis of CAD Models

Abstract

The paper deals the exercising Virtual Reality (VR) validation for ergonomic study of Computer Aided Design (CAD) virtual environment models, for the safe and comfortable operations for human. The CAD based virtual environments will subject to ergonomic analysis could reduce the costs of testing and errors in integration of sub systems compared to real-time trials. In this venture, a Digital Human Model Simulation (DHMS) was analysed in a workspace by incorporating VR simulation softwares. A transport and freight of military personnel and equipment in Armoured Personnel Carrier Vehicles (APVCs) model was employed as environment for ergonomic assessment. VR device with head-mounted display was used to perform the ergonomics analysis in virtual environment. The ergonomics study and the experience lead to changes in design features. This application could benefit in the defence, aerospace and naval sector, where ergonomically viable compact spaces for human inhabit of key importance.
