mistuning

[mis′tün·iŋ]
(mechanics)
The difference between the square of the natural frequency of vibration of a vibrating system, without the effect of damping, and the square of the frequency of an external, oscillating force.

Effect of mistuning are omitted and therefor system is considered with fully cyclic symmetry.
Vibrato may contribute to the tendency of listeners to allow for more mistuning from singers than from violinists, but researchers have yet to test for that possibility.
Afterwards the 11 presenters demonstrated different HCF problems and their mitigations based on either the traditional redesign approaches or advanced solutions, such as frictional damping technology or intentional blade mistuning.
The adjustment of the parameter [DELTA]l was used to tune the mistuning of the resonant frequencies of coupled single-mode resonators that are equivalent to the dual-mode resonator.
In this regard Tenney invokes the mechanism of tolerance, familiar from cognitive psychology, which holds that - within a certain tolerance range, or range of frequencies - some slight mistuning is possible without altering the harmonic identity of an interval.
People learn to accept a limited amount of musical mistuning as still being in tune, with vocalists getting an especially big break.
In his 14 years of research, he has successfully addressed a wide array of problems, in particular developing comprehensive simulation techniques of random processes and fields, devising new probabilistic approaches for the analysis of the random mistuning effects in turbomachinery blade vibrations, introducing and applying structural identification techniques to flow-induced vibration problems, and analyzing the characteristics of spinning beams and plates.
The two studies further demonstrated that, as the mistuning of a harmonic is gradually increased to about 130 cents (8%), virtual pitch gradually returns to its original position (i.
