Sentence examples for modal parameters and from inspiring English sources

The simulation results are experimentally validated using both modal parameters and frequency response functions (FRFs).

The posterior most possible values of modal parameters and their uncertainties were estimated through Bayesian inference.

The identified modal parameters and model updating results were analyzed and are discussed in detail.

Results are generated to characterize the response behavior with respect to the modal parameters and structure design of PWB.

Therefore we are interested in analyzing the natural frequencies, damping ratios (modal parameters) and level of accelerations of those components.

Both modal analysis and harmonic response analysis are performed to obtain the structural modal parameters and frequency response functions, respectively.

In this paper, two subspace-based methods are considered that take these statistical uncertainties into account, first modal parameter and their confidence interval estimation for a direct comparison of the structural states, and second a statistical null space based damage detection test that completely avoids the identification step.

It is apparent that the proposed equation is formulated only by small amount of available structural information such as the undamaged mass and stiffness matrices and also modal parameters before and after the damage.

The right-hand side of Eq. (26) is an N × N matrix that consists of the undamaged mass matrix and corresponding modal parameters before and after occurrence of structural damages.

As a result of expanding these mentioned equations, the perturbation matrices are determined only by undamaged mass and stiffness matrices as well as modal parameters before and after of damages.

This method could identify the most probable value (MPV) of modal parameters efficiently and also calculate the associated posterior uncertainty analytically, providing an important tool to evaluate the accuracy of modal parameters.
