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.

摘要： In a liquid-filled anti-vibration mounting device suitable such as for an engine mount, an accommodation room containing a rubber movable plate is formed inside a partition member partitioning a liquid chamber into a pressure receiving chamber and a balancing chamber. The partition member includes a pair of division walls, one adjoining the pressure receiving chamber and the other adjoining the balancing chamber. Each division wall is formed with a plurality of communication holes. The communication holes are arranged to undulate at least a portion of the movable plate towards the peripheral edge thereof at specified circumferential intervals or greater by the action of the liquid pressure through the communication holes. The movable plate thus deformed, particularly its portion towards the peripheral edge, has a small area to come into contact with the division walls at a time, which effectively disperses and lessens a shock due to contact.
