process and device for dynamic calibration equipment to control the dynamic behaviour of tyres

摘要

provision is made for calibration of a dynamic apparatus (1) for the control of the behavior of tires.comprising a rotating drum (9) arranged to act in relation to push on a tire (5) driven in rotation.and dinamometriche cells (10) connected to an electronic processing unit (12) to detect the dynamic forces transmitted to the tire (5) of the drum (9).the calibration is carried out by applying on the drum (9), a predetermined static load and then transmitting to the drum of predetermined frequency cyclical dynamic forces.intensity and dynamic change.cyclical forces produced by an eccentric (20) transmits a reciprocating to a pad (22) related to the handling dinamometriche cells (10) by springs (29,31).the signals emitted by the cells dinamometriche (10) are recorded and stored by the processing unit (12).to obtain data to compare with the signals emerging during the test of a tire (5).
