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.
