Application of a FRF Based Model Updating Technique for the Validation of Finite Element Models of Components of the Automotive Industry 951246
This paper presents two applications of the RADSER model updating technique (ref. 1). 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.
The first application deals with the identification of the dynamice characteristics of rubber mounts.
The second application validates a coarse finite element model of a subframe of a Volvo 480.
