Attenuation Of Grass Trimmer Handle Vibration Using Imposing Node Technique

Prolonged use of grass trimmer exposes the user to the risk of hand-arm vibration syndrome. Imposing node technique was investigated in order to achieve low vibration (node) at the grass trimmer handle location. It is established that, for the grass trimmer system which can be modelled as a beam, t...
