Suspension
Test Description
The objective of the measurements was to measure the vibration in the wheel (unsprung mass) and the vehicle (sprung mass). The data includes vibration and acceleration measurements of both the sprung and unsprung masses. In the first video, the vehicle travels on a cobblestone road at approximately 40 km/h. The second video shows the vibration and displacement of both masses on the same road. IRI indicates the road roughness level, which is the source of excitation on the wheel. The data has been organized in Excel spreadsheets for further analysis, whether using Excel itself or exporting to programs like Matlab or Python, for example.
The measurements are free and available for unrestricted use. We kindly request that you credit ‘Laboratory of Vehicle Systems at UFSC’ when using the material.
The vehicle used in the test is the 2015 Renault Sandero Expression 1.6 16v Sce.
