Analysis of Hand Held Power Tools for Reducing the Vibration and Force in the Human Hand Arm Systemud

摘要

The main objective of this analysis is to find out the effect of hand held power tools on hand arm and reducing the effects of these hand held power tools on hand arm of the operator. Three different power hand held tools a Jigsaw, a Planer and a Random orbital sander were used for analysing the effects on hand arm. Two measurement tools were used a Fingertip tactile pressure sensor for measuring the forces acting on the hand arm and A Tri-axial accelerometer for measuring the vibration caused by these tools in hand arm. To reduce the effects of the hand held tools on hand arm of the operator different coatings on the handle of hand-held power tools including one handle uncoated will be used and then the measurements of vibration and force obtained from these coated handle is then compared with the uncoated handle
