SYSTEM AND METHOD FOR CHARACTERIZING THE FLEXIBILITY LAW OF A SUSPENSION OF A VEHICLE TRAIN

摘要

A system (SC) is used to characterize a suspension of a wheel (TV) train (RV) of a vehicle (V) including a body (CV). This system (SC) comprises: measuring means (A1, A2, CD, CF) measuring at least one relative displacement between this wheel (RV) and a part of the body (CV) and the forces exerted by the wheels ( RV) on a support (SV), - lifting means (ML) able to lift from a selected height a part of the vehicle (V) including the train (TV), and - the analysis means (MA) own following the separation of the vehicle (V) from the lifting means (ML), to identify a flexibility law of the suspension from the measurements.
