适用范围

This procedure is applicable to modes from 500 and 13@000 Hz. The parameters measured with this procedure are defined as the damping factor@ ??for first nine vibration modes of the beam. The measurement will be done in free-free conditions and with temperature. Purpose This SAE Recommended Practice is intended to establish a standardized and repeatable method for performing damping measurements on a brake insulator. The insulator is bonded to a standardized steel plate and the procedure measures the Frequency Response Function (FRF) of the specimen with insulator and the damping is calculated at the resonance frequencies. The measurements are performed at different temperatures and the damping of the insulator is hence established as a function of temperature and frequency.
