Abstract
In this work, a finite element modal analysis of motorcycles in various configurations - frame only, frame with engine, frame with engine and handlebar - is carried out using general purpose FE software. Experimental modal analysis (EMA) is performed on the actual physical systems in the above configurations. The results from the analytical FE models are compared with those derived from the experimental models. Good correlations are demonstrated for the analytical models up to 250 Hz using modal parameters - natural frequencies and mode shapes. Techniques for updating the finite element models that yield improved correlation with test data are explored. Further, it will be shown that good quality component models are necessary, but not sufficient, for realizing full-vehicle models that could predict vibration responses accurately. It is demonstrated that the connector modeling is very essential in building good assembly level models. It is shown that the complete vehicle model of motorcycle that is built with updated assemblies can be effectively used to trouble shoot problems, thus reducing the product development time.
