An oblong cantilevered support includes a pair of latitudinally spaced apart oblong resilient members connected by a pair of longitudinally spaced apart blocks. The longitudinal spacing between the blocks can be adjusted. One or both of the members can have a tapered profile causing the stiffness of the member to vary along its length. Adjusting the spacing between the blocks and/or sliding a variable stiffness member longitudinally with respect to the blocks can adjust the stiffness of the overall support. Each member can be made from a unitary piece of fiber composite material such as a carbon fiber infused polymer wherein the orientations of the fibers are varied to provide both bending and torsional strength and stiffness that varies along the length of the member. The tapered geometry can be formed by a pair of parallely spaced apart oblique trapezoidal truncated pyramids interconnected by a webbing strip.

A shock isolation cushion has two basal components and at least one shock isolation tier. The two basal components are disposed at an interval. The at least one shock isolation tier is disposed between the two basal components and is sequentially stacked from one of the two basal components to the other one of the two basal components. Wherein each of the at least one shock isolation tier has multiple shock isolation units. Each of the multiple shock isolation units has a supporting section and at least two buffering sections. The at least two buffering sections respectively extend from two opposite ends of the supporting section. Each of the at least two buffering sections is curved to form an opening between the buffering section and the supporting section.

The present disclosure discloses an electromagnetic multistage adjustable variable inertance and variable damping device. Iron cores are magnetized by winding electromagnetic coil windings outside the iron cores and applying an electric current action to the electromagnetic coil windings, and air gap magnetic fields are generated by the magnetized iron cores and permanent magnets in air gaps to cause the variation of shear damping forces between a driving shear plate and magnet yokes and between driven shear plates and magnet yokes, which avoids that the mechanical properties of an inerter cannot be fully utilized due to the friction caused by mutual contact among parts, thereby realizing multistage real-time adjustability of an instance coefficient and a damping coefficient of the device.

An oblong, resilient, semi-rigid cantilevered support member can have a pair of spaced apart tapering rods joined by a medial webbing strip. The strip can have a substantially planar back surface tangent with the back edges of the tapering rods to form a substantially quadrangular and planar back side to the member albeit with rounded side edges. The strip can have a generally trapezoidal front surface that is scalloped in a concave manner. The member can be made from a unitary piece of fiber composite material where the orientations of the fibers are varied to provide both bending and torsional strength and stiffness that varies along the length of the member. The member can be coupled to a second latitudinally spaced apart oblong resilient member connected by a pair of longitudinally spaced apart blocks for greater adjustability.
