摘要： A system that determines a road surface profile based upon filter coefficient data from noise cancellation systems is disclosed. The system includes a filter coefficient monitoring module that is configured to receive a first set of filter coefficient data from an noise cancellation module. The system also includes a road surface profile module that is configured to receive an input representing a road surface type and generate a road surface profile based upon the road surface type and the first set of filter coefficient data and to store the road surface profile including a correspondence between the road surface type and the first set of filter coefficient data.

摘要： A system for determining dynamic properties of a chassis component includes a first fixture, a second fixture spaced from the first fixture, and a chassis component arranged between the first and second fixtures. The chassis component has a first end arranged at the first fixture and a second end arranged at the second fixture. A shaker system is arranged at the first end of the chassis component. A first multi-axis force transducer is arranged between the shaker system and the chassis component. The first multi-axis force transducer includes at least a 3 degree of freedom (DOF) sensing capability. A second multi-axis force transducer is arranged between the second end of the chassis component and the second fixture. The second multi-axis force transducer includes at least a 3 degree of freedom (DOF) sensing capability. A controller is coupled to the shaker system, and the first and second multi-axis dynamic force transducers.

摘要： Methods and systems are provided for determining frequencies associated with tire crown bending. The system includes a vibration generating device configured to excite vibrations through a tire. The system further includes a vibration sensing arrangement configured to sense vibrations at a plurality of sensing points on the tire. A computer is in communication with the vibration sensing arrangement and configured to determine a first frequency associated with bending of the crown of the tire based at least partially on phase differences between the sensed vibrations at the plurality of points on the tire.

摘要： The present disclosure is directed to a system and a method for spectral shaping of vehicle noise cancellation. In an example implementation, the method includes determining a center frequency of an expected tonal peak within a selected noise band based upon vehicle data, generating a noise cancellation signal using a weighted shaping filter to shape the noise band, and outputting the noise cancellation signal to smooth the expected tonal peak.

摘要： A panel assembly includes a first panel defining a surface, and a boom attenuation panel. The boom attenuation panel includes a circumferential edge, and a central portion. The boom attenuation panel is attached to the surface of the first panel, along the circumferential edge of the boom attenuation panel. The central portion of the boom attenuation panel is spaced from the surface of the first panel a gap distance to form a gas chamber between the surface of the first panel and the central portion of the boom attenuation panel. The gas chamber contains a gas that is moveable within the gas chamber in response to wave-like motion of the first panel. Movement of the gas increases the effective acoustic mass of the boom attenuation panel, and damped the wave-like motion of the first panel, which operates to reduce noise generated from the wave-like motion of the first panel.

摘要： A wheel assembly for a vehicle and a method of manufacturing the wheel assembly for the vehicle are disclosed. The wheel assembly includes a rim and a tire. The tire includes a distal wall, a first side wall and a second side wall, with the first and second side walls extending from the distal wall and each of the side walls attached to the rim such that the distal wall is spaced from the rim to define an interior cavity between the tire and the rim. The wheel assembly also includes a resonator defining a hole such that the resonator presents an inner wall defining a boundary of the hole. The hole cooperates with the interior cavity. The resonator includes an insert mounted to the inner wall. The insert defines an aperture in fluid communication with the interior cavity for attenuating sound produced inside the interior cavity.
