摘要： A helical compression spring has an outer diameter between 15 and 50 mm. The helical compression spring comprises a helically coiled steel wire. The diameter d (in mm) of the steel wire is between 2 and 5 mm. The steel wire comprises a steel alloy, consisting out of between 0.8 and 0.95 wt% C; between 0.2 and 0.9 wt% Mn; between 0.1 and 1.4 wt% Si; between 0.15 and 0.4 wt% Cr; optionally between 0.04 and 0.2 wt% V; optionally between 0.0005 and 0.008 wt% B; optionally between 0.02 and 0.06 wt% Al; unavoidable impurities; and the balance being iron. The steel alloy has a carbon equivalent higher than 1. The carbon equivalent is defined as: C wt% + (Mn wt% / 6) + (Si wt% / 5) + (Cr wt% / 5) + (V wt% / 5). The microstructure of the steel wire in the helical compression spring is drawn lamellar pearlite.

摘要： A lamina emergent torsional (LET) joint that includes an integrated membrane to reduce, or eliminate, certain unwanted motions and/or displacements associated with the operation of the LET joint is disclosed. The membrane-integrated LET joint (i.e., M-LET) can be used as a hinge for a lamina emergent mechanism and/or as a surrogate fold for an origami application to ensure accurate and repeatable transitions from a planar (i.e., lamina) state to a non-planar (i.e., lamina-emergent) state, and vice versa.

摘要： 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. A flexure structure 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.
