    Abstract: Disclosed are vehicle steering column assemblies with viscous dampers, methods for making and for using such assemblies, and motor vehicles with steering column assemblies having viscous dampers. A steering column assembly is disclosed that includes a first shaft member that connects to a steering wheel/handle, and a second shaft member that connects to a vehicle body. These shaft members are telescopingly connected such that one shaft member selectively translates longitudinally with respect to the other shaft member. A viscous damper assembly is interposed between the two shaft members. The viscous damper assembly includes a damper housing with first and second reservoir volumes disposed inside the housing. Multiple constricted flow channels fluidly connect the reservoir volumes. Viscous fluid flows from the first reservoir volume, through the constricted flow channels, to the second reservoir volume in response to relative vibrational displacement between the shaft members to thereby viscously attenuate vibrational energy.

    Abstract: Methods and apparatus are provided for attenuating translational vibration in a steering system. The apparatus can include a housing having a fluid chamber, a recess and a mounting bracket that couples the housing to a hand wheel of the steering system. The fluid chamber can be in communication with the recess. The apparatus can include a mass disposed in the recess of the housing, which can have a fixed stiffness. The apparatus can include a damping fluid disposed in the housing so as to flow between the fluid chamber and the recess. The mass can be movable in the damping fluid, and the damping fluid can have a variable stiffness. The apparatus can further include a control module that determines a translational vibration experienced at the hand wheel and outputs a signal to vary the stiffness of the damping fluid in response to the translational vibration in substantially real-time.

    Abstract: A panel assembly includes a first panel and noise attenuation panel that is attached to the first panel. The noise attenuation panel includes a central portion having a length and a width. The central portion of the noise attenuation panel is spaced from the surface of the first panel by a gap distance to form a gas chamber between the surface of the first panel and the central portion of the noise attenuation panel. The panel assembly includes at least one wall structure that is disposed within the gas chamber. The wall structure extends between the central portion of the noise attenuation panel and the surface of the first panel, and includes a pattern that defines a fluid flow path through the gas chamber, which includes an effective length that is greater than both the length and the width of the central portion of the noise attenuation panel.
