  • Patent number: 10677310
    Abstract: A vibration isolator mechanism is provided for limiting transfer of vibrations from a first element to a second element coupled to the first element. The vibration isolator mechanism may include a vibration isolator structured to provide a quasi-zero/negative stiffness response to a force applied to the vibration isolator when the applied force is within a predetermined range. The vibration isolator mechanism may also include a force application mechanism structured to apply a force to the vibration isolator. The vibration isolator mechanism may also include a force adjustment mechanism structured to adjust the force applied to the vibration isolator by the force application mechanism so that the applied force is within the predetermined range.

  • Patent number: 10371229
    Abstract: An adjustable vibration isolator for limiting transfer of vibrations from a first element to a second element coupled to the first element. The isolator includes conical disc spring members, each having a first end including a central opening, a central axis, and a second end opposite the first end. The second end includes an outer edge of the spring member. A spacer is coupled to each spring member so as to enable a transfer of forces between the spring member and the spacer. Spring member deflection resistance mechanisms are operable to adjustably resist movement of the outer edges of the spring members in directions radially outwardly during loading of the spring members. Resistance of movement of the outer edges of the spring members enables control of a force required to deflect the spring members, and control of the force-deflection curve of the vibration isolator.

  • Publication number: 20190186589
    Abstract: An energy-absorbing structure for a vibration isolator includes a conical disc spring member having a first end including a central opening and a second end opposite the first end. The structure also includes at least one spacer having a base portion with a first side. The base portion first side defines a cavity structured to receive therein a second end of the spring member. The cavity has a floor, and a second end of the spring member is positioned in contact with the floor. The floor includes an opening formed therein and positioned so as to reside opposite the first end of the spring member when the second end of the spring member is positioned in contact with the cavity floor. The opening is structured to receive at least a portion of the first end of the spring member therein during an inversion of the spring member.
