Abstract
The primary objective of the study is analytically predicting the anti-vibration coating on the handles and to evaluate the vibration isolation effectiveness. The ISO 10068:2012 two-point driving human physical models are coated with Foam-A material, Foam-B material, and Gel material. The coated ISO models are applied to predict the effectiveness of three different anti-vibrations coating in terms of vibration transmitted to the finger, palm, and the shoulder. The results are obtained as a vibration transmissibility magnitude in the three orthogonal directions (xh, yh, zh) and the results are also compared with uncoated models. A significant level of vibration reductions was found. The proposed model may also be useful for further analysis of anti-vibration coating materials and help designers to develop better handles for vibrating tools.
Highlights
Hand operating tools such as drills, grinders, road breakers are highly transmitting large magnitude of vibration to the hand-arm system
The influence of grip force and amplitude of vibration is quantified when the system subjected to sinusoidal excitations using the driving point mechanical impedance technique (DPMI) [4]
This study primarily aims to predict the vibration response of the hand-arm system while using different anti-vibration coating to the vibrating tools or machines
Summary
Hand operating tools such as drills, grinders, road breakers are highly transmitting large magnitude of vibration to the hand-arm system. To understand the mechanisms behind vibration-induced disorders, the bio-dynamic responses of the hand-arm system is to be considered and effective knowledge is required for the better development of assessing the vibration risk [2, 3]. The influence of grip force and amplitude of vibration is quantified when the system subjected to sinusoidal excitations using the driving point mechanical impedance technique (DPMI) [4]. Most of the research studies have considered vibration excitation at a single point in the hand-handle interface for deriving the driving-point bio-dynamic response data [7, 8]. The anti-vibration gloves can be used to reduce the vibration exposure and essentially serve as a simple active suspension system between the hand and the tool [9]
