Sentence examples for modal testing methods from inspiring English sources

The 3D DIC technique provides non-contact full-field measurements on complex surfaces whereas conventional modal testing methods employ point-wise frequency response functions.

Since the importance of the directivity of the modal parameters of rotor systems associated with rotor rotation has not been fully understood, the classical modal testing methods which apply to non-rotating structures have been applied to rotor systems to evaluate the modal characteristics of rotor systems.

The validity and the performance of the proposed non-contact modal testing method are checked with several experiments.

It was found that the modal testing method was capable of characterizing the elastic constants of mass timber panels with at least 90% agreement with the results via conventional static tests.

In this study, the moduli of elasticity (MOE) in major and minor strength directions (Ex and Ey), and in-plane shear modulus (Gxy) of 51 industrial size cross laminated timber (CLT) panels, 4 multi-ply solid wood panels (MSWP) were measured by a modal testing method.

The directivity information of the modes carried in the directional frequency response functions is used in a modal testing method of rotating disks which is proposed for separation of the forward and backward travelling wave modes and identification of the diametrical node numbers associated with modes of interest.

A frequency offset was generated because of the error introduced by model manufacture and installation, and a proposed modal test method was used to eliminate the frequency offset.

A modal test method that uses sound pressure transducers at fixed locations and an impact hammer roving over a test structure is developed in this work.

Modal testing is a useful method to investigate dynamic properties of a cutting tool system and improve material removal rate.

One of the most popular excitation methods for modal testing of rotating machinery is known to be the uncorrelated isotropic excitation, which requires two independent random sources with equal power for generation of a pair of uncorrelated excitation signals.

An efficient identification method for modal testing of viscoelastic composite materials is demonstrated in this paper, through the analytical experimental transfer function method.
