Research on Digital Human Model System Used for Heavy Commercial Vehicle Ergonomic Design

Abstract

A generic framework of digital human model system is studied by adopting the knowledge of anthropometry,multi-body system kinematics,computer graphics and ergonomics. The problems during the application of current digital human models in vehicle ergonomic design are analyzed,which are taken into account in subsequent research. Theories and corresponding techniques about how to use human data during design process to ensure enough accommodation level are studied. The content,method and performance evaluation of heavy commercial vehicle ergonomic design are studied and summarized. Based on the above mentioned theories and techniques,the system for heavy commercial vehicle ergonomic design (SHOVED),a digital human model system used for ergonomic design of heavy commercial vehicle,is developed,including functions of human modeling,vehicle modeling,scheme design,scheme analysis and optimization. By application of SHOVED,not only heavy commercial vehicle ergonomic design process can be done effectively and perfectly,but also the level of target people accommodation can be held accurately. The profile,constitution,key techniques and application principle of the generic digital human model framework and SHOVED are presented. Prospects for further study are given.
