A feasibility study on elastokinematic parameter identification for a multilink suspension

Abstract

In this paper an algorithm for the kinematic analysis of a multilink suspension taking joint compliance into account is presented. The analysis can be pro. tably used in an identi. cation procedure to determine elastokinematic parameters starting from experimental data. The proposed identification algorithm is based on the solution of a typical non-linear least-squares problem. Inorder to test the feasibility of this procedure, a multilink suspension, modelled by a multibody dynamics code, is employed as the experimental data source. Some joint stiVness values are determined to provide an example of the algorithm's application.
