Exeter vibration mode analysis device for the car

摘要

The subject innovation relates to a Exeter for the mode of the car analysis, and more particularly, to suppress the noise due to the self-oscillation of Exeter for measurement of vibration and increase the sound insulation, than analysis of a car mode can be achieved by accurate measurement for relates to Exeter soundproofing.; The subject innovation is connected to the vehicle's power transmission element in the analysis mode Exeter for measuring the emission sound is added to a given vibration,; Surrounding and spaced apart at predetermined intervals in the outer peripheral surface of the Exeter a vacuum case;; Is interposed between the outer peripheral surface of the vacuum case and Exeter comprises a vibration-proof member for absorbing vibration,; If between the Exeter outer surface and the vacuum case is to provide Exeter soundproofing for modal analysis of a car, characterized by being a vacuum, a power transmission element in order to measure the radiation sound applies a predetermined vibration, the vibration in the Exeter itself is generated, then the vibration is absorbed by the anti-vibration member in close contact with the outer peripheral surface of Exeter, this residual vibration and noise is suppressed between the vacuum casing forming the vacuum.; Accordingly, this way, consisting of Exeter soundproofing for modal analysis of the vehicle is possible to suppress the vibration and noise generated in the Exeter improve the sound insulation effect, it is possible to accurately detect the emitted sound of the object for Modal Analysis, Design of there is an advantage that can increase the accuracy.
