ABSTRACT:
A vibratory device operating as a two mass vibrating system having an exciter mass and a work member mass spring coupled and supported by isolator springs and operating at a frequency less than the natural frequency of the system. Two or more cylindrical elastomer springs are mounted on a center beam of the work member having a spring rate in the shear direction for setting the required natural frequency and also provide a spring rate in the compression direction that will have a natural frequency substantially above the natural frequency in the shear direction. The cylindrical elastomer springs mounted to a single rigid center beam provides flexibility of design for a specific work member application.
