摘要： A method for noise cancellation includes monitoring a system for a current operating point, monitoring the system for a predetermined disturbance, and in response to the predetermined disturbance, determining the disturbance to be in one of a transient or steady state response period. A set of data is selected corresponding to the current operating point of the system, the disturbance, and the response period from a database containing predetermined noise cancellation waveform data. A noise cancelling waveform is output to audio transducers based upon the selected set of data.

摘要： 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.

摘要： 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.

摘要： A system includes a stationary component, a rotating component arranged adjacent the stationary component, and a planetary torsional vibration absorber system mounted between the stationary component and the rotating component. The planetary torsional vibration absorber system includes a planetary gear system including a ring gear, a sun gear and a carrier. At least one of the ring gear, the sun gear and the carrier is rotationally fixed to the rotating component and another of the ring gear, the sun gear and the carrier is fixedly secured to the stationary component. A tuned vibration absorber including a tunable damping and stiffness component and an inertia ring is mounted to yet another of the ring gear, the sun gear and the carrier.

摘要： A vehicle, a prop-shaft and a method of reducing noise in a vehicle are provided. The prop-shaft includes a cylindrical shaft having a hollow interior. A liner is positioned within at least a portion of the hollow interior. A first retaining member is disposed adjacent an end of the liner, the first retaining member sized to inhibit movement of the liner in a first direction. A second retaining member is disposed adjacent an opposite end of the liner from the first retaining member, the second retaining member sized to inhibit movement of the liner in a second direction, the second direction being opposite the first direction.

摘要： 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.
