Abstract

This study is conducted to perform the use of paddy straw fiber as an additional damper to reduce vibration transmissibility from hand-held power tools. Hand Arm Vibration (HAV) contributes the consequences of neurological damages such as prolonged shiver towards the part of body that has been exposed to that vibration transmissibility. In this study, fabrication of the gloves with additional damper of paddy straw fiber and sponge is developed as to suppress the vibration from transmit palm of the hand with the means of innovation. Material preparation is conducted at different composition for the test of such differences between those compositions added on these gloves. The purpose of the preparation method is to test and analyze the effectiveness of using paddy straw fiber as an additional damping in reducing the vibration transmissibility from hand-held power tools. A conceptual design was made to aid the manufacturing process in terms of sewing and comfort of using this prototype. Data collected is analyzed using Pro-Photon Vibration Spectrum Analyzer Software to achieve the objectives on comparing its vibration transmissibility behaviour. Vibration transmissibility is calculated using vibration reduction index equation. Of which has its lowest transmissibility of vibration is the best composition on justifying the use of paddy straw fiber as an additional damper from hand-held power tools. Therefore, the use of paddy straw fiber is more effective in a range of 40% to 80% composition by mass of paddy straw fiber.
