摘要： In an abnormal noise inspection method for a anti-vibration device for vehicle use, it is determined whether, during travel of a vehicle in which a supported member is supported to the vehicle body by an anti-vibration device, abnormal noise occurs or not in the passenger compartment owing to the anti-vibration device. The method includes: an input step of mounting to a shaker the anti-vibration device before assembled into the vehicle and then inputting vibrations in a predetermined pattern to a supported member-side mounting part of the anti-vibration device; a measurement step of measuring, during the inputting of vibrations, a transmission force output from a vehicle body-side mounting part of the anti-vibration device; an analysis step of frequency analyzing time-series data on the measured transmission force to obtain the power spectrum of the transmission force; and a determination step of estimating, based on the power spectrum of the transmission force and according to a predetermined evaluation criterion, whether a vehicle produces abnormal noise in the passenger compartment when it runs with the anti-vibration device mounted thereon.
