Imposing node technique is applied to the grass trimmer shaft in order to achieve very low
vibration (node) at the handle location. The optimum tuning frequencies of the two tuned …

A major occupational health risk in the agricultural industry is Hand Arm Vibration Syndrome
(HAVS), which is brought on by exposure to vibration from handled machinery. This review …

Mechanical systems subject to vibration are prevalent across many industries. Although
potentially different in application, they sometimes share the need to minimize aspects of …

In the design of a typical dynamic absorber, the components corresponding to the dynamic
vibration absorber (DVA) should be reduced to a lumped constant system model comprising …

Traditionally, hand-held impact machines (HHIM) such as pneumatic breakers have little or
no means of vibration reduction. Consequently, vibration injuries are a common problem for …

Prolonged exposure to the orbital sander with high vibration level can lead to the Hand-arm
Vibration Syndrome (HAVs). In order to attenuate the vibration when using the orbital …

This paper presents a novel approach to the design of an active suspended handle by
identifying the effective frequency range, based on the saturation effects of the piezo stack …

A theoretical model of a base system consisting of two isolators and a beam is established.
To improve the isolation performance of the base system, distributed dynamic vibration …

The purpose of this investigation is to apply imposing node technique for vibration reduction
of petrol engine grass trimmer handle using vibration absorber. The algorithm is devised to …

Vibration neutralizers provide an effective method of attenuating tonal vibrations within a
structure. In this paper, variable stiffness vibration neutralizers are used to impose zero …
