The measurement of vibration transmissibility and mechanical impedance of resilient materials as a function of coverage area to improve anti-vibration glove design

摘要

This work describes the results of experimental tests on the dynamic behaviour of three different resilient material samples with the aim of estimating their effectiveness in reducing the vibration transmission for operators of power tools wearing anti-vibration gloves. The experimental study maintains the constant vibration amplitude level and loading mass on the samples as per ISO 13753 [1] and by changing the amount of material in the sample, investigates the relationship between the amount of sample material, the material impedance and the resulting vibration transmissibility. Further investigation shows that vibration transmissibility of the tested samples is also a function of the area of the sample material. The measured vibration impedance of the material can then be used to estimate the vibration transmissibility of a glove design embedded with the sample. The results and analysis improve the understanding of the material dynamic behaviour for hand-arm applications and can be used to ascertain the required parameters for designing quality anti-vibration gloves.
