Evaluating the effects of different types of hand gloves and handle grip materials on hand-arm response while operating hand grinding machines

Abstract

Abstract

 The objective is to evaluate different hand gloves and handle grips of polyurethane materials on hand arm response while operating hand held grinding machines. The hand arm response was investigated in terms of fingertip force using FingerTPS systems. Cotton, Nylon and Leather gloves were initially evaluated for choosing the best, and further trials were conducted with that set of gloves and additional polyurethane foam handle grip of four densities. Thirteen healthy male subjects were chosen for the study on a standardized work piece. In the first set of trials, the leather gloves gave the maximum reduction 57.9 % and in the second set of trials, in combination with the handle grip of polyurethane foam of density D120 gave 84.7 % reduction of the force on the fingers. The pneumatic grinding machine operators can use a combination of leather gloves and handle grip of polyurethane foam of density D120 to reduce the hand arm vibration.
