Creating a 3-D Digital Human Model for Truck, Bus and Heavy Machine Design 2001-01-2822
A truck or bus driver’s designed workspace must meet ergonomic federal regulations as well as provide a safe and comfortable working environment for the entire potential driver population. As more trucks, buses and heavy machinery are being designed completely within 3-D computer-aided design (CAD) environments, it is essential to also address ergonomics in a 3-D digital environment. Three-dimensional digital human models (3DDHM) allow designers to visualize and ergonomically assess the interaction between operators and the vehicle workspace in digital design environments. This paper outlines the process of creating a valid 3DDHM for truck, bus and heavy machine design. Proper tool application stems from a thorough understanding of how the tool was developed.
