Application of a FRF Based Model Updating Technique for the Validation of Finite Element Models of Components of the Automotive Industry

Abstract

<div class="htmlview paragraph">This paper presents two applications of the RADSER model updating technique (<span class="xref">ref. 1</span>). The RADSER technique updates finite element model parameters by solution of a linearised set of equations that optimise the Reduced Analytical Dynamic Stiffness matrix based on Experimental Receptances.</div> <div class="htmlview paragraph">The first application deals with the identification of the dynamice characteristics of rubber mounts.</div> <div class="htmlview paragraph">The second application validates a coarse finite element model of a subframe of a Volvo 480.</div>
