Optimizing Working Conditions in Construction Machines Using a CAD-based 3D Man Model

The layout of special-purpose vehicles for global distribution has to ensure that all products can “fit” worldwide operators. Since spring 2001, BOMAG has implemented RAMSIS software, a CAD-based 3D man model, into the conception and design phases for their construction machines. First applications comprised the ergonomic optimization of the configuration and layout for driver's cabs and control elements, specifically related to a small single drum roller, a tandem roller, a big refuse compactor and in addition maintenance issues. First results of the enhanced design process highlighted the benefits of applying such ergonomic tools, providing anthropometrical and additional human data for consideration in the layout of workplaces.
