A selectively tunable vibration absorber includes a support member having an outer surface, and a selectively tunable element mounted relative to the outer surface of the support member. The selectively tunable element is selectively adjustable to attenuate vibrations in a selected frequency range perceived by the support member in a selected direction. A mass is supported by the selectively tunable element.

Selectively tunable vibration absorber for a vehicle

A vehicle includes a chassis, and a drivetrain supported by the chassis. The drivetrain includes a prime mover and a transmission mechanically linked to the prime mover. At least one dynamically adjustable engine mount connects the drivetrain to the chassis. The at least one dynamically adjustable engine mount includes a selectively adjustable parameter. One or more sensors is associated with the vehicle. The one or more sensors is operable to detect one or more vehicle parameters. A control system is operatively connected to the at least one dynamically adjustable engine mount and the one or more sensors. The control system is operable to alter the selectively adjustable parameter of the at least one dynamically adjustable mount to substantially isolate the chassis from lateral shudder of the drivetrain in response to the one or more vehicle parameters.

Dynamically adjustable engine mounts for a motor vehicle

A vehicle includes a chassis and a vehicle body supported by the chassis. At least one dynamically adjustable body mount connects the vehicle body to the chassis. The at least one dynamically adjustable body mount includes a selectively adjustable parameter. One or more vehicle sensors is associated with the vehicle. The one or more vehicle sensors is operable to detect one or more vehicle parameters. A control system is operatively connected to the at least one dynamically adjustable body mount and the one or more vehicle sensors. The control system is operable to alter the selectively adjustable parameter of the at least one dynamically adjustable body mount to substantially isolate the body from road and vehicle induced vibration in response to at least one of the one or more vehicle parameters and the one or more road surface parameters.
