Table 1 presents the time period for the first two modes of vibration
with a fixed aspect ratio [n/b = 1.
This partly explains why the presentation of the experimental results on vibrating systems is often confined to only the few lowest modes of vibration
on the frequency scale.
For these samples, we were able to observe vibration patterns from some of the modes of vibration
in a vacuum.
Modes of vibration
of transducer fixed along perimeter were calculated (Fig.
It is known that the amortizations had little influence on own pulsations and on their modes of vibration
A piston vibrates the melt at different stages during cooling, according to modes of vibration
programmed in a computer attached to the piston controllers (see section 3.
Khanna & Sharma  calculated frequencies for first two modes of vibration
with parabolic thickness variation and bi-parabolic temperature variation.
The distribution coefficients for the natural modes of vibration
Phase difference between the channel signals should also be alternating, so that it would be possible to create different modes of vibration
of the elements.
Some modes of vibration
are preponderant moving on the vertical plane, others are on the horizontal plane and some are moving on both planes.
are characteristics of principal modes of vibration
In machine diagnose the main characteristics offered by transfer function are (Sutter et al, 2005): dynamic rigidity or compliance, resonance frequencies, damping factor, natural modes of vibration
