Abstract: A shock isolator includes slots in inner and outer parts that define flexures between the parts. The slots may include inner slots and outer slots that are offset from each other around a perimeter of the inner part. The shock isolator also includes stops that provide a mechanical limit on the movement of the flexures. The stops may be posts that extend from one of the parts into holes in the other of the parts. In another embodiment that stops may be extensions from one of the parts over portions of the other of the parts. The stops help in preventing plastic bending and/or fracture of the flexures due to stress.

Abstract: An isolator device comprises a first mount coupleable to an input structure subject to shock and/or vibration energy, a second mount coupleable to an object to be isolated (e.g., an electronics device). A flexure structure is coupled between the first and second mounts, and comprises a plurality of parallel flexures, a series of flexures, and a plurality of transition portions, all defining an isolation path between the first and second mounts. The parallel flexures are tuned to resonant frequency to attenuate shock and/or vibration in an axial direction relative to a normal axis. The series of radial flexures are tuned to resonant frequencies to attenuate shock and/or vibration energy in both radial directions relative to the normal axis. The isolator device can be a single piece of metallic material. An elastomeric damping material can be disposed within openings defined by the flexure structure to dampen response at the isolator's resonant frequency. Associated systems and methods are provided.
