Experimental investigation for vibration attenuation for power tools

Abstract

Construction zones are often buzzing with "chatter"emanating from different machines. The most commonly used machines are hand-held power tools that handle materials such as bricks, concrete, and other masonry-related materials. The labourers are exposed to vibrations from the device during operation for a prolonged period, causing lasting damage to the hand-arm system. Many factors lead to the unpredictable behaviour of the machine, making it difficult to manoeuvre. Increased gripping forces result in the hand-arm system being a better vibration medium. To counteract this effect, smart materials can stabilise the system. Magnetorheological Elastomers are one such material that can solve the problem of stabilising the device as they can adapt to different conditions, providing semi-active isolation for a wide range of frequencies and demonstrating its force-dependent behaviour. A handle made of MRE can be used to replace the conventional handle at the chuck region. This paper presents how the handle behaves in static conditions under the influence of different magnetic fields for an impact hammer test. © 2025 Author(s).
