An energy-absorbing structure for a vibration isolator includes a conical disc spring member having a first end including a central opening and a second end opposite the first end. The structure also includes at least one spacer having a base portion with a first side. The base portion first side defines a cavity structured to receive therein a second end of the spring member. The cavity has a floor, and a second end of the spring member is positioned in contact with the floor. The floor includes an opening formed therein and positioned so as to reside opposite the first end of the spring member when the second end of the spring member is positioned in contact with the cavity floor. The opening is structured to receive at least a portion of the first end of the spring member therein during an inversion of the spring member.

Presented herein, inter alia, are suspension system components having tuned accumulator sizing and/or stiffness. Such suspension system components are envisioned for use in a distributed active suspension system of a vehicle. In particular, through appropriate sizing of accumulators of a suspension system component of a vehicle, ride quality of the vehicle may be improved and so called “rough ride” issues may be precluded. Alternatively or additionally, various valves or alternative compliant mechanisms may be included in the suspension system component, so that desirable performance may be obtained for a range of operating conditions.

A suspension assembly for a cycle having improved stability includes a steering fork having a first arm and a second arm, each of the first arm and the second arm having a fixed pivot and a shock pivot, the space between the first arm and the second arm defining a wheel opening. A shock link has a shock link fixed pivot and a shock link floating pivot. A shock absorber has a shock gas spring comprising a shock spring body a shock gas piston having a first gas piston area, a spring unit having a spring gas spring comprising a spring body and a spring gas piston having a second gas piston area. A gas pressure inside the shock gas spring is equal to a predetermined pressure for a user's body weight to produce optimal ride conditions for the user's body weight.

A method for monitoring a shock strut may comprise measuring a first shock strut pressure, measuring an ambient temperature, measuring a shock strut stroke, measuring a second shock strut pressure, and determining a servicing condition of the shock strut based upon the first shock strut pressure, the ambient temperature, the shock strut stroke, and the second shock strut pressure, wherein the servicing condition indicates whether it is desirable for the shock strut to be serviced with at least one of a liquid and a gas. The first shock strut pressure and the shock strut stroke may be measured before the takeoff event with a weight of an aircraft supported by the shock strut.

A damping valve device having a support with a circumferential groove in which a radially expandable annular element together with a flow surface forms a restriction, which restriction transitions from an open position to a restriction position depending on the flow velocity of a damping medium, and the maximum expansion position of the annular element is determined/limited by a stop. The annular element moves in direction of the open position with a delay when the flow velocity decreases by means of a dead time element.

A vibration isolator mechanism is provided for limiting transfer of vibrations from a first element to a second element coupled to the first element. The vibration isolator mechanism may include a vibration isolator structured to provide a quasi-zero/negative stiffness response to a force applied to the vibration isolator when the applied force is within a predetermined range. The vibration isolator mechanism may also include a force application mechanism structured to apply a force to the vibration isolator. The vibration isolator mechanism may also include a force adjustment mechanism structured to adjust the force applied to the vibration isolator by the force application mechanism so that the applied force is within the predetermined range.

Provided is a damper with which the energy efficiency for attenuating input vibration corresponding to the unsprung resonance frequency and the sprung resonance frequency can be improved. Also provided is a method for manufacturing this damper. In this damper the electrical resonance frequency, as specified by the inductance of an electromagnetic motor and the capacitance of a capacitor, is set within 20% of the unsprung resonance frequency, thereby enabling the input vibration corresponding to the sprung resonance frequency as well as the input vibration corresponding to the unsprung resonance frequency to be reduced.
