ABSTRACT:
An isolator for use in a hand-held vibrating device for providing optimum vibration isolation by utilizing elastomeric sections. Six embodiments are shown which utilize elastomer sections to enhance vibration isolation along an axial direction of vibration. A first embodiment includes a frustoconical section, while the second employs a W-shaped buckling element. A third embodiment includes use of a tuned fluid inertia which is tuned to substantially coincide with a predominant operating frequency of the vibrating device and produces forces to substantially reduce the vibration transmission, while three other embodiments employ metallic buckling springs. Another embodiment employs a tuned vibration absorber and still another combines a tuned mass with a buckling column.
