Natural frequency Natural frequency is the term used in the vibration when there will be no friction in the way of the vibration, and it will define as the square root of the spring constant to the mass of the system, and when there is damping, then it will...
Because of the complexity of the mathematical expressions, the literature concerning the free vibration analysis of a uniform beam carrying a “single” two degrees-of-freedom (d.o.f.) spring–mass system is rare and the publications relating to that carrying “multiple” two-d.o.f. spring–...
Natural Frequency This parameter for a single degree of freedom is given by ωn=k/m. Increasing the mass reduces ωn, and increasing the spring constant k increases it. From a study of the damped system, the damped natural frequency ωd=ωn1−ζ2 is lower than ωn. View chapterExplore...
Computation of natural frequencies of multi degree of freedom system Wear and tear of machinery manifests into vibrations or changing the pattern of vibrations. Analysis of vibrations for frequency response and time response has become indispensable for major process machinery in trouble shooting. Computa...

Previous work by the author with Sparrow and Russell, and by Strasberg and Feit, has suggested that internal mass per unit natural frequency is the appropriate prime descriptor of the internal structure of a complex system enclosed by a shell. In the simplest idealization one conceives of many ...
