Nr 1

44-53

The paper proposes usage of existing methods of test data analysis into post-processing of FE models results, as we 11 as usage ofimproved methods ofFE data identifications for test data analysis. Continuously growing size and complexity ofthe FE models and possibilities of new technologies like laser or camera measurement of vibrations need new methods in identification, comparison and correlation. Generalised work flow of NVH analysis and 18 steps of proposed methodology are presented. Every step is described using graphics pictures generated from FEgraph software dedicated as post-processing tool for automotive industry. The proposed methods of same data processing for test and analysis data was successfully introduced into automotive industry and is on continuous development. Nevertheless, it can be used in the other branches of industry including in the analysis ofthe strength calculations oj the rail vehicles bodies.
