METHOD OF VEHICLE VIBROACOUSTIC ANALYSIS WITH AUTOMATED TRANSMISSION GEARBOX AND IMITATOR FOR IMPLEMENTATION THEREOF Russian patent published in 2018 - IPC G01M13/02 

FIELD: metrology.

SUBSTANCE: group of inventions refers to metrology. Carry out a series of preliminary arrivals and record the parameters of the external noise of a vehicle in a measured area. Carry out preliminary identification and ranking of noise sources. Vehicle is installed in an anechoic chamber on a horizontal platform with the distancing of its driving wheels from the surface of the site. Based on the results of preliminary identification and ranking of noise sources, set control points where accelerometers are installed. In the speed dialing mode, preliminary measurements and recording of the vibration acceleration parameters recorded by the accelerometers at the specified control points are performed on the recording device. Dismount the driving wheels and replace them with imitator of the wheel drive. Perform the re-measurement and recording on the recording device of the vibration acceleration parameters recorded by the accelerometers at given control points. After the completion of the repeated measurements and recording vibration acceleration parameters, compare them with the preliminary measurements of the vibration parameters and preliminary identification and ranking of sources of external noise.

EFFECT: broader functional capabilities.
