Abstract :
There is very high impaction to hand when nailing with air nailer. The shape of handle can affect the stress distribution on hand significantly. Hand fatigue and even hurt may be caused if the poor designed tool is used for long time. The 3D model of hand and handle is imported to ANSYS 10.0 to simulate the stress and strain distribution on hand. The shape of the handle is redesigned according to the simulation result. The result shows that the finite element method can be used in the ergonomical evaluation of handle.
