Resonance Oscillations

The process of resonance oscillations of a cantilever-fixed polymer rod with a rectangular cross section is considered. The values of the resonant frequencies of the own oscillations of the rod were obtained. The possibility of determining the real and imaginary parts of a complex dynamic Young's modulus of a polymeric rod at basic resonance frequency is shown.

Dynamic Young's Modulus

A theoretical study of a method based on the “compound resonance” principle for the measurement of the dynamic Young's modulus of short staple fibers is presented. The system considered is a fixed-free cantilever spring coupled at the free end to the fiber. Representing the fiber as a Voigt element and neglecting the losses in the cantilever spring, it is shown that both the real and imaginary parts of the dynamic modulus of the fiber can be calculated from the amplitude or velocity response of the system to forced vibrations in the neighborhood of resonance.
