摘要： An isolator for use in a hand-held vibrating device for providing optimum vibration isolation by utilizing elastomeric buckling sections which operate in a buckled mode during normal use. The buckled elastomer sections significantly reduce the spring rate within an operating load range thus substantially reducing the vibration transmitted to the user. Six embodiments are shown which utilize buckling 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 amplified counter inertial forces to substantially reduce the vibration transmitted to the user, 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. A first embodiment of a front grip isolator that is used with the buckling isolator for reducing the radial mechanical vibration transmitted to the front hand of the user, also utilizing buckling sections, is taught. A second embodiment of the grip isolator has buckling sections with low combined axial stiffness to provide both radial and axial vibration isolation.
