Mass Properties Identification of a Rigid Body Using Modal Analysis

In performing vibration analysis of the car engine on the engine support, it is necessary to know the mass properties of the engine including mass, position of the center of mass and mass inertia moments. Because the car engine has a relatively complex geometric shape and is composed of different components with different densities, determining its mass properties faces many challenges. There a...

Optimal Sensors Location Using Modal Assurance Criterion in Modal Identification of Concrete Gravity Dams

Determination of the optimal sensors location in order to identify of modal parameters, especially in large structures such as dams, is one of the practical issues, which is widely used in damage detection and structural health monitoring. The main objective of this study is to obtain the most information from the dynamic response in a concrete gravity dam by minimizing the non-diagonal element...

Operational Modal Analysis using a Fast Stochastic Subspace Identification Method

Stochastic subspace identification methods are an efficient tool for system identification of mechanical systems in Operational Modal Analysis, where modal parameters (natural frequencies, damping ratios, mode shapes) are estimated from measured ambient vibration data of a structure. System identification is usually done for many successive model orders, as the true system order is unknown. The...

Output-only Modal Analysis of a Beam Via Frequency Domain Decomposition Method Using Noisy Data

The output data from a structure is the building block for output-only modal analysis. The structure response in the output data, however, is usually contaminated with noise. Naturally, the success of output-only methods in determining the modal parameters of a structure depends on noise level. In this paper, the possibility and accuracy of identifying the modal parameters of a simply supported...

dynamic analysis of sandwich constructions using a modal method

in this paper dynamic analysis (modal-method) of sandwich contructions have been studied. for this purpose a computer program was developed that could analyse the sandwich construction's dynamics. by using the program, one can find the natural frequencies, the normal modes and dynamic response of the free and forced vibrations.by solving few problems in this article, we have illustrated th...
