This work is devoted to the modal analysis of a pre-stressed steel strip. Two different complementary ap-proaches exist in modal analysis, respectively the theoretical and experimental modal analyses. On the one hand, the theoretical modal analysis is related to a direct problem. It requires a model of the structure.
Experimental Modal Analysis (EMA) modal model, a Finite Element Analysis (FEA) modal model, or a Hybrid modal model consisting of both EMA and FEA modal parameters. EMA mode shapes are obtained from experimental data and FEA mode shapes are obtained from an analytical finite element computer model.
Experimental modal analysis of an aircraft wing prototype for SAE . It is performed through theoretical (analytical or numerical) and experimental approaches. The theoretical technique uses the description of a physical model, which is composed of the mass, rigidity and damping [12]. The modal
the finite element method is known for computing modal analysis; if will be collected through the test of system input and output signal through the parameter identification obtained modal parameters, known for experimental modal analysis. Computational modal analysis method has been applied in many product developments, espe-

A modal analysis will be correlated with a test when the frequency and the mode shape is correlated. The tool used to compare shapes is the MAC (modal assurance .
Modal analysis can be performed both by analytical techniques (using finite element analysis), [5] [6] and by experimental techniques, both types of analysis practically leading to the same modal parameters.

modal analysis. The prepared composite is first cut into pieces to make specimens for impact hammer modal anal-ysis. The dimensions of the specimens are 250 mm along the length and 25mm along the width at a 3 mm thickness. To carry out the modal analysis 5 such specimens are pre-pared [15-18]. The experimental modal analysis of the specimen is
This paper concentrates on both experimental and analyticalmodal analysis of a crankshaft. Analytical work involved the development of a three-dimensional FE model.A modal analysis was performed to provide frequenciesand mode shapes. Results of the FE modal analysis werecompared with those obtained from the EMA. 2. Crankshaft Description
