NONLINEAR VIBRATIONS OF A VISCOELASTIC ROD WITH QUADRATIC ELASTICITY

摘要

A study is made of the effect of the constant component and the second harmonic on the vibrations of a Voigt rod with quadratic elasticity and linear viscosity in the case of monoharmonic excitation at the frequency of the principal linear resonance. A numerical algorithm is proposed to solve one-dimensional problems on the vibrations of viscoelastic bodies taking into account higher harmonics.
