Sentence examples for modal parameters in from inspiring English sources

Moreover, modal parameters in terms of natural frequencies and associate loss factors are given through the transversal displacement.

The least-squares complex exponential method is used for the extraction of modal parameters in the time domain.

During the last 20 years, the development of experimental modal analysis techniques has facilitated the accurate measurement of modal parameters in many types of structure.

In this paper, we have explored the mechanism of gear excitation and determined the relationship between the rotational speed and gear׳s modal parameters in centrifugal fields.

The results illustrate that this recursive algorithm can obtain the modal parameters in the high signal noise ratio (SNR) and it has better computational efficiency than the SVD method.

We show that the accuracy and precision of our OMA technique is higher compared to traditional methods and that it allows evaluating the evolution of modal parameters in operational conditions.

The change is characterized by changes in the modal parameters, i.e., modal frequencies, modal damping values and mode shapes associated with each modal frequency.

The difference in the identified damage results is mainly due to the significant difference in the identified modal parameters used in the three cases.

In contrast with most existing SDIMs which require the modal parameters measured in both intact and damaged states, the present SDIM may require only the FRF-data measured at damaged state.

Thus, the estimate of yield displacement and modal parameters used in the initial design can be updated using values computed in the analysis of the first design.

However, when using modal parameters only in model updating, a difficulty arises regarding safety assessment and response prediction of local structural members.
