摘要

This work presents the development of a new method which makes use of Scanning Laser Doppler Vibrometry (LDV) for the indirect measurement of the shape of the tire sidewall in the rolling condition.rnScanning LDV is widely adopted for the measurement of vibrational Operational Deflection Shape (ODS) in rolling tires using either the Eulerian or the Lagrangian approach. Residual effects of geometry are usually removed by an AC coupling.rnThis paper presents a new approach in LDV velocity data processing that allows the processing of the velocity data obtained with a Scanning LDV in the Eulerian approach on a rolling tire in order to obtain not only ODS but also static shape.rnThis technique does not require additional sensors or systems since it is based only on signal processing.rnThe uncertainty of the obtained result is also evaluated and a comparison with a state-of-the-art solution in shape measurement is presented.
