Vibration transmissibility reduction module with flexure mechanism for personal tools

In many mechanical operations, vibrations from personal tools may cause serious injuries to the human body. This is particularly true in the case of vibrations that are constantly and repeatedly transferred to humans. In fact, a serious physical problem, Raynaud’s phenomenon, may occur. In this pape...

Description
Summary:In many mechanical operations, vibrations from personal tools may cause serious injuries to the human body. This is particularly true in the case of vibrations that are constantly and repeatedly transferred to humans. In fact, a serious physical problem, Raynaud’s phenomenon, may occur. In this paper, we propose a vibration transmissibility reduction module with a flexure mechanism for personal tools. First, a target personal tool, that is, a grass cutter is selected, and the level of vibration transmissibility to the hand is measured. Subsequently, we develop a concept design of the module with stiffness to reduce the vibration transmissibility by more than 20%. The vibration transmissibility is measured by an accelerometer. In addition, the vibration reduction is enhanced when the gap between the inner and outer bodies is filled with silicone gel. Finally, this is verified experimentally.
