Abstract: In this paper, small oscillations of needles on an elastic base are considered, taking into account dissipation in the case of a suddenly applied force, an equation of motion and its solution are proposed, the dynamism coefficient and its max-ima are determined.
Keywords: oscillations, equation of motion, needle, base, dynamism coefficient.
The aim of this work is to study the vibrations of needles embedded in an elastic base. To determine the dynamic coefficients in the first approximation, we represent the needle in the form of an elastic non-inertial beam, rigidly fixed at one end, carrying a concentrated mass at the point of application of the shock load.
- Materials and methods
The equation of small oscillations of such a system, taking into account the dissipation in the case of a suddenно applied force, will be as follows [1]
