  • Damping Coefficient
    Use for time delay applications. Damping coefficient is almost always the primary determinant for applications where a specific time delay is required. Airpot > Damping Coefficient.

  • Shifting Critical Speed Out of the Operating Range by Changing From Tilting Pad to Sleeve Bearings (.pdf)
    One property of heavily to moderately loaded sleeve bearings is the resulting asymmetric stiffness and damping coefficients. These asymmetric properties often result in split first critical speeds. Since the horizontal stiffness is much softer than the vertical, a horizontal first critical speed

    solutions) and solid elastic materials. That's because these so-called viscoelastic materials have a hybrid of qualities. Purely elastic materials store energy during loading then fully return when the load is removed. In contrast viscoelastic materials have a high damping coefficient that returns
