A can bodymaker includes a housing assembly, a drive mechanism, a ram assembly, a domer assembly, and a ram body dampening assembly. The ram assembly includes an elongated ram body. The drive mechanism is operatively coupled to the ram assembly so that the drive mechanism imparts a reciprocating motion to the ram body. The ram body dampening assembly is disposed adjacent the ram body path of travel. The ram body dampening assembly includes a housing and a dampening member. The dampening member is disposed immediately adjacent the ram body path of travel.

A damper device is capable of attenuating fluctuations in torque. The damper device includes a first rotor and a second rotor rotatable relatively to the first rotor. The damper device also includes a plurality of elastic members elastically coupling the first rotor and the second rotor. The second rotor is rotatable relatively to the first rotor while held by the first rotor with use of the plurality of elastic members.

Methods and apparatus are provided for a shock attenuation device configured to operate between a structure and a mass that is supported by and moveable relative to the structure in a guided manner along a stroking direction. In one embodiment, a notch load portion is configured to provide a resisting force to relative displacement of the supported mass over a first stage stroking distance according to a predefined load profile that includes a spike load peaking at a first threshold load value at the onset of relative displacement, and a substantially constant notch load for a remainder of the first stage stroking distance. A constant load portion arranged serially with the notch load portion is configured to provide a substantially constant resisting force to displacement of the supported mass at a second threshold load value over a second stage stroking distance, wherein the second threshold load value is higher than the first threshold load value.

A resetting semi-passive stiffness damper (RSPSD) triggering assembly and a RSPSD and method of use for damping movement of an object. Exemplary embodiments of a RSPSD triggering assembly include, for example, a rotatable disc and a spring-loaded lever arranged between the disc and a slotted channel. A sensor is provided and communicates with a bypass valve on the cylinder. A change in the direction of movement of the disc causes reciprocation of the lever in the channel, which causes the sensor to send open and close signals to the bypass valve. In some embodiments, a single disc may be replaced with two interacting discs. A RSPSD equipped with such a triggering assembly is usable to damp movement of an object of interest.

The drive mechanism is operatively coupled to the ram assembly so that the drive mechanism imparts a reciprocating motion to the ram body. The ram body dampening assembly is disposed adjacent the ram body path of travel. The ram body dampening assembly includes a housing and a dampening member. The dampening member is disposed immediately adjacent the ram body path of travel.

No numbers found in figures. An example vehicular shock absorbing apparatus includes a shock absorber, a hydraulic mount operatively coupled with the shock absorber, a first decoupler movably disposed in a first portion of the hydraulic mount, and a second decoupler movably disposed in a second portion of the hydraulic mount.

An air spring includes a closing member, a rolling piston, and an air spring bellows connected to the rolling piston and the closing member to form a fluid-filled pressure chamber. A level control system for supplying and/or discharging fluid may be integrated into the pressure chamber to control level position based on air spring stroke. The level control system may have a control valve and an actuator connected to the control valve. The actuator may include a guide tube coupled to the rolling piston or closing member, and movably arranged within the pressure chamber. An actuating member may include a pin member and may operate the control valve. A compression spring may have a central spring and a biasing spring, and the guide tube may include a control flange coupled to the pin member, and the biasing spring may be supported to press the pin member against the control valve.

A damping assembly for a structure includes a housing with a first fixed end and a second movable opposite end. A first translatable portion of the housing is slidably movable relative to an adjacent second section of the housing, the former being fixedly secured to a base when the structure is under load. A viscous damper disposed within the housing is engaged only after the first translatable section has first moved beyond an initial predetermined distance indicative of a higher amplitude loading event. At least one biasing feature prevents the viscous damper from operating until the first translatable section has first moved beyond the initial predetermined distance.

A handling strut connects the powertrain of an automobile to a structural member, such as a panel in the engine bay. The handling strut is comprised of two strut members, one connected to the powertrain, the other connected to the structural member. A shaft attached to one strut member, extends through a bushing provided in the other strut member and an air gap is provided between the bushing and the shaft, such that when the engine is idle, or not accelerating, and in the absence of hard cornering, the strut members are decoupled. The isolation of the strut members when not required to control engine roll, reduces/avoids transmission of noise, vibration and/or harshness.
