Case Study Analysis: "Scuttle Shake Analysis of Open Cars by OMA"

Scuttle shake analysis of open cars using OMA (Operational Modal Analysis).

We would like to introduce a case study by F-MA Consulting, a specialist in vibration noise analysis technology, titled "Scuttle Shake Analysis of Open Cars Using OMA (Operational Modal Analysis)." The definition of scuttle shake is: "a phenomenon commonly seen in open cars with low body rigidity," "which manifests as a 'shaking sensation' when driving in urban areas at speeds of 40 to 60 km/h," and "is generally said to be caused by low-frequency (10 to 20 Hz) twisting modes of the body." 【Experimental Analysis Using ModalVIEW】 - Collection of acceleration and deceleration data from actual vehicle runs at each measurement point - Pole extraction using SSI from time history data - Calculation of mode shapes at each point from the extracted modes - Display of vibration modes in the operational state For more details, please contact us or download the catalog.
