    摘要: This study developed a passive vibration reduction method to provide the damping capability
    for precision manufacturing equipment in an economical manner. The structure of the damping
    device is simple, which does not require changes in the frequency of the external force. An elastic
    medium was sandwiched between the bottom of the main component and the underlying plate
    or membrane. This combination results in a damper capable of reducing vibrations in the
    precision manufacturing equipment. We analyzed the influence of the elastic modulus and
    geometry of the elastic medium in the plate–plate or plate–membrane system on the damping
    capability. Among the various dampers considered herein, the combinations that include stiffer
    foams and a flexible membrane provide the greatest damping capability, far exceeding that of
    the metal plates. The results also show that the damping capacity offered by a rectangular frame
    with a diagonal x-shaped elastic medium is close to that of a full sheet.
