A method taken from [7] will be used to determine the vibration parameters of a spring whose last coils are covered with an elastomeric coating. This is an approximate method based on decomposition of the problem. In the first approximation, in order to find the form of vibrations, both ends of the spring are assumed to be stationary, which is justified by the high ratio of the amplitude of coil resonance vibrations to the vibrations of the mass and the base. In [8],
it has been demonstrated that internal damping, whose values can be obtained using elastomeric coatings, does not cause significant phase shifts of the dislocations of individual spring points. In addition, internal damping does not change the form of vibrations, so only a very small error is made when a model without damping is assumed for calculations. Energy losses can be estimated using the internal damping model. By multiplying the elastic energy values obtained for three sections of the spring by the appropriate equivalent specific damping capacities ψ, we obtain the dissipated energy for one period of vibration ΔUE. In the second approximation, the movements of the lower end of the spring are no longer ignored, which allows us to calculate, in turn, the force that the spring exerts
