Description
Summary:The General Engineering and Systems Analysis Company (GESAC), Inc., under contract with the Human Research and Engineering Directorate of the U.S. Army Research Laboratory (ARL), (contract number DAAL01-94-P-0906) estimated body joint loading using a computer simulation program called DYNAMAN(copyright). This work was performed in support of the U.S. Army Chemical and Biological Defense Command (CBDCOM) modular decontamination system (MDS) development program. The objective of this effort was to model the loading imposed by each of five different scrub brush systems on various human body joints and compare the resulting force and torque values. Of primary interest was information concerning how electric motor placement affected joint loading and how the joint loads of the powered brush systems compared with those of the manual brush. The results of this modeling effort identified several limitations with the current model, identified several key aspects of power scrub brush design and operator interface, and were used to aid in the selection of brush designs for continued development.
