  • Spring having a high natural frequency and a low spring rate
    Publication number: 20020195760
    Abstract: A compound spring is disclosed that has the benefit of a low preload force and a relatively high natural frequency. In its most basic form it is a helical spring having a cylindrical section and a tapered section. In the preferred embodiment the preload force is linear with increased spring deflection and the spring is unaffected by the harmonics of the surrounding machine. Deflection in the axial direction is a small percentage of the free length. In the preferred embodiment the wire cross-section is constant.
