Natural Frequencies of Mindlin Circular Plates
Journal of Applied Mechanics, 1980The natural frequencies of vibration based upon the Mindlin plate theory are tabulated for uniform circular plates with free, simply supported, and clamped edges for the first several tens modes.

Natural Frequencies of Uniform Grillages
Journal of Applied Mechanics, 1963The natural frequencies for the transverse vibration of grillages with various types of boundary conditions are studied, taking into account the distributed mass of the beams. Finite-difference calculus is used for deriving the frequency equations.

The Multiplanar Nature of Frequency
Glottotheory, 2016Abstract As reflected by the distinction between types and tokens, frequency is standardly conceived of in a two-dimensional fashion. This conception draws on the linguistic hierarchy in that token frequency is calculated at a higher structural level than type frequency. The fact that the linguistic hierarchy consists of more than two

Computation of Natural Frequencies
2015The frequencies at which a PKM tends to vibrate when hit, struck or somehow disturbed are known as the natural frequencies. The determination of the natural frequencies of PKM is needed for both design and control purposes. In this chapter, we present the computation of natural frequencies of parallel robots.

Natural frequency analysis of a human tibia
Journal of Biomechanics, 1980Abstract A beam type finite element computer model is used to predict the natural frequency response of a human tibia with varying geometries, mass formulations and boundary conditions. Results are compared to analytic solutions and to published computer and experimental results.

The natural frequencies of grillages
International Journal of Mechanical Sciences, 1968Abstract This paper presents a method for the determination of the natural frequencies of grillages, which may be skew. It could be used, for example, to find the natural frequencies of a skew road bridge, within the limits of any assumptions taken. The cross girders are assumed to be simply supported between the longitudinals which themselves may be

Frequency of Naturally Occurring Strabismus in Monkeys
Journal of Pediatric Ophthalmology & Strabismus, 1985ABSTRACT A colony of Macaca nemestrina monkeys was screened for naturally occurring strabismus. Thirteen cases of naturally occurring strabismus were documented, 12 esotropes and one exotrope. The characteristics of the strabismus in these monkeys were similar to those of human clinical cases.

In order to explain magnetic frequency relationships, development of cumulative frequency curve and its statistical interpretation are discussed; from frequency curve, relation between magnitude and design period in years is derived; applicability of procedure is shown by sampling from 1023-yr period of tree-ring indexes.

Aircraft Engineering and Aerospace Technology, 1949
THE aim of this paper is to calculate the natural frequencies and to consider the influence of the damping parameter on a wing's natural flexural and torsional vibration. The author took into account only the elastic hysteresis of the material because the structural damping, depending on the type of the aeroplane, cannot be taken into account in a ...

Journal of Fluids Engineering, 1930
Abstract The natural frequency of machine parts as related to the noise problem in machine operation is discussed in a general manner. Vibration phenomena in disks and rings are described in detail, following which the author discusses the manner in which a gear vibrates at its natural frequency.
