A flex cell for absorbing energy from an applied force includes a panel attached to a flex cage. The flex cage is made from a resilient material that allows deformation of the flex cage when a force is applied to the flex cell. The flex cell is attachable to a support surface. In some instances, the flex cell is detached from the support surface when sufficient force is applied to the flex cell.

A mount bushing includes an outer mounting ring adapted for connection to a mount structure. An outer structural ring is disposed inside of the outer mounting ring. A main elastomeric isolation arrangement is disposed between the outer structural ring and an inner structural insert, wherein the main elastomeric isolation arrangement is supported between the outer structural ring and the inner structural insert by elastomer material. An outer ring isolation layer of elastomer is disposed between the outer mounting ring and the outer structural ring, wherein the outer ring isolation layer is isolated from the main elastomeric isolation arrangement by the outer structural ring. A mounting bolt is inserted through a bore in the inner structural insert.

Disclosed is a damper structure in contact with a connection unit for coupling a first coupling structure part and a second coupling structure part, including a damper part formed of an elastic material and at least one fixing part coupled to at least one surface of the damper part and protruding outward, and coming into contact with the connection unit and moving toward the damper part by pressure applied by the connection unit when the connection unit is separated or fastened.

Torsion spring device includes an outer housing, an inner housing located in the outer housing, and an elastic element. The elastic element supports the inner housing relative to the outer housing such that a restoring force is built up between the outer housing and the inner housing as a result of a deflection caused when the outer housing and the inner housing are rotated relative to one another. The restoring force-deflection curve can be adjusted by a choice of shape and/or material of the outer housing, of the inner housing, and of the elastic element and/or wherein the hysteresis can be adjusted by a choice of shape and/or material of the outer housing, of the inner housing and of the elastic element.

A shock isolator is arranged between two automated coupler parts in a vibration testing unit. When the coupler parts are engaged and coupled during vibration testing of a component, the shock isolator is disabled, and when the coupler parts are disengaged and decoupled after vibration testing, the shock isolator is activated to absorb excess shock energy and prevent shock transfer between the coupler parts that would damage the test component. The shock isolator includes a bushing that is inserted in a lower part of the two automated coupler parts and a compressive fit rod that is press-fit into the bushing. The bushing has a chamfered volume and the compressive fit rod has a corresponding compressible volume that is displaced into the chamfered volume to disable the shock isolator. After vibration testing, the compressive fit rod is expandable to a regular shape to activate the shock isolator.

The present invention is directed to a spray boom for an agricultural machine in which the boom is arranged as a truss with interior diagonal struts of the truss being configured to absorb tension and compression energy imparted by deflections over the length of the boom with such energy being dissipated as heat. In one aspect, the diagonal strut could comprise a rod moveable with respect to a tube with a polymer, such as an elastomeric material, arranged in the tube to dampen the movement. The tension and compression of the diagonal strut could subject the dampener to a shearing force which could be absorbed by the dampener rather than transferred to the machine.

A wave spring unit comprising a plurality of annular wave-spring elements stacked vertically along an axial direction, which is characterized in that each of the annular wave spring elements of the wave spring unit comprises crest portion and trough portion formed alternately in a horizontal axial direction; said crest portion and trough portion of adjacent vertically annular wave spring elements are positioned opposite each other; said adjacent vertically annular wave spring elements have the same or different from each other in at least one physical parameter selected form a strip thickness, a strip diameter, a strip weight, strip shape, wave contact number, edge shape, overall shape of the spring and a combination of wave and helical spring; and the wave spring unit has a maximum compression up to 30.2 mm and is capable of bearing load up to 2680.2 N.

Various embodiments of the present technology may provide methods and apparatus for a 3D-printed spring. The 3D-printed spring may be formed from a plurality of toroidal elements spaced apart from each other and connected with a plurality of connectors. Each connector connects one toroidal element to a directly adjacent toroidal element.
