    摘要： Springs of different types are provided with the ability to dynamically change stiffness. A number of embodiments feature hollow tubing wherein stiffness change is accomplished due to the pressure change inside the tubing which affects the stresses in tubing walls. In other embodiments inside pressure change causes variability in tubing's cross-section shape and size leading to large changes in stiffness. A number of embodiments feature spring coil diameter variability achieved by a variety of means and resulting in highly substantial changes in stiffness and for some embodiments spring length variability thus providing them with actuation capability in addition to stiffness variability.

    摘要： Apparatus for absorbing shock, particularly repetitive shocks, comprises a frame and a shock-absorbing component comprising a shape memory alloy (SMA). In one type of apparatus, one or more SMA rings (65) are mounted on brackets (64) on a frame (62, 63) so that shock received by the frame from one direction changes the shape of the rings into ellipses with major chords in a first direction, and shock received by the frame from the opposite direction changes the shape of the rings into ellipses with major chords in a second direction which is at right angles to the first direction. In other types of apparatus, SMA shock-absorbing components (16, 27, 37, 46, 89) are mounted in a frame (11, 12,13,14,15,17, 21, 22, 24, 25, 26, 31, 32, 34, 35, 41, 42, 43, 44, 45, 47) so that the way in which the shock-absorbing component is deformed is independent of the direction of the shock received by the frame. The shock-absorbing components preferably include a superelastic SMA, optionally in combination with a martensitic SMA. The apparatus is useful for a wide variety of purposes, including the protection from shock of medical devices, electronic assemblies, vehicles, bridges and buildings.

    摘要： A vibration and shock isolator may include a resilient member and a compressing member. The resilient member may be connected between a vibrating source and an object. The compressing member may provide the resilient member with a compression displacement in accordance with the vibration characteristics applied to the resilient member from the vibrating source to change stiffness of the resilient member. Thus, a designed natural frequency of the isolator may be simply changed using the shape memory wire to suppress vibration amplification. As a result, the isolator may effectively relieve the shock and the vibration so that a structural stability of a structure may be ensured. Further, the isolator may have a simple structure so that the isolator may have improved reliability and durability.

    摘要： An oscillation decoupling device is disclosed with a load-receiving element which is mounted in an oscillating manner relative to a support unit at least along an active direction along which at least part of the load is applied having at least one sensor unit which detects an oscillation of the element due to the load and at least one actuator unit acting against the oscillation of the element. The support unit is modularly configured and serves as a support structure for at least one unit that receives the element and is elastically deformable in the active direction of the load. The load-receiving element is connected to the elastically deformable unit. The at least one actuator influences the deformation applied to the at least one unit, or is integrated thereon, so that the at least one actuator initiates a deformation acting against an elastic deformation due to the load inside the unit.
