Summary:

Accurate finite element model of a structure is required in order to carry out its dynamic design at the computer level. It has been observed that due to various approximations made in the Finite Element model the predicted values of the dynamic characteristics quite often differs from that of the actual structure. In view of this, the FE model is updated in the light of the test data from Experimental modal analysis (EMA) so as to improve its correlation with the test data. In this paper updating of a FE model of a two wheeler chassis structure is presented. Chassis is considered in the assembled condition with engine, suspension and tires. First an approximate FE model is constructed followed by modal analysis on the structure. FE Model updating is then carried out using Inverse Eigen sensitivity Method. Updated model predictions are found to resemble closely with the experimental results
