- •
Tool, workstation, and task parameters were measured for 35 tools, representing 69 installations in an automotive assembly plant.
- •
The dynamic forces acting against the human tool operator and resulting handle reaction deflections were predicted using a biodynamic tool operator model.
- •
The proportion of threaded fastener tool operators capable of maintaining published psychophysically derived deflection limits were ascertained.
- •
While handle deflection did not exceed the limit for most installations, changes in tool speed and operator position improved the six jobs that did.
