1. acoustics The basic frequency of a vibrating object or sound as opposed to its harmonics, or the principal component of a complex sound wave. 2. The frequency of vocal fold vibration at the glottis, unaffected by resonance. See also: optimal pitch Medical Dictionary for the Health Profe...
so that said coupling springs constantly exchange energy with both of said screening baskets during their oscillatory motions and thereby cause a system comprising the screening baskets, the resilient supporting means, said coupling means and the resilient bars to have a natural frequency of vibration;...
In this research, using a new topology optimization method based on the homogenized material with a penalty factor and the chessboard prevention strategy, we obtain the optimal material layout of a thin square plate for the natural frequency of a certain free vibration mode. The volume fraction ...
Mobility=x˙jFk complex, frequency-dependent ratio of vibration velocity to force. It is possible to derive a single equation that links the forced and free vibration characteristics of the mdof (Ewins, 1984): (5.114)Yjk(ω)=x˙j(ω)Fk(ω)=iω∑r=1N(rϕj)(rϕk)λr2−ω2 r...
