A feasibility study on elastokinematic parameter identification for a multilink suspension

摘要

In this paper an algorithm for the kinematic analysis of a multilink suspension taking joint compliance into account is presented. The analysis can be profitably used in an identification 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. In order to test the feasibility of this procedure, a multilink suspension, modeled by a multibody dynamics code, is employed as the experimental data source. Some joint stiffness values are determined to provide an example of the algorithm's application.
