METHOD FOR ASCERTAINING THE DEFORMATION OF A TYRE SUBJECTED TO AN EXTERNAL STRESS WHILE ROLLING

Disclosed is a method for ascertaining the deformation of a tyre, the method comprising the following steps: - fastening a sensor, which is capable of generating a signal representative of movement of the sensor, to the tyre; - acquiring (201) a temporal wheel rotation signal SigTDR (101) comprising...

Beschreibung
Zusammenfassung:	Disclosed is a method for ascertaining the deformation of a tyre, the method comprising the following steps: - fastening a sensor, which is capable of generating a signal representative of movement of the sensor, to the tyre; - acquiring (201) a temporal wheel rotation signal SigTDR (101) comprising the amplitude of the acceleration while rolling; - determining a reference speed Wreference (202) associated with a portion of the wheel rotation signal SigTDR; - normalising (203) the portion of the wheel rotation signal SigTDR by a magnitude that is a function F of Wreference; - angularly resampling (204) the portion of the wheel rotation signal SigTDR; - obtaining the spectral signal (205) of the portion of the normalised and angularly resampled wheel rotation signal SigTdR; - defining a spectral magnitude (206); - identifying the deformation of the tyre Def% (207) as a function G of the spectral magnitude.
