The transverse oscillations of a viscoelastic bar under the action of a follower force are considered. The constitutive relation is the non-linear relation between the stress, strain and strain rate, where the non-linear part is described by a homoge

Two stability problems are solved. In the first, the stability of mechanical systems, on which dissipative, gyroscopic, potential and positional non-conservative forces (systems of general form) act, is investigated. The stability is considered in th

The stability of mechanical systems, on which dissipative, gyroscopic, potential and positional non-conservative forces act, is investigated. The condition for asymptotic stability is obtained using the Lyapunov function and an estimate of the domain

The stability of equilibrium of mechanical systems driven by dissipative, gyroscopic, conservative and non-conservative positional forces is investigated. Proofs are presented of several general theorems of an asymptotic nature, which state whether t

In this paper we study a stability of low oscillations of cantilever viscoelastic beam one end of that is rigidly fixed and another one is subjected to action of the constant by absolute value tracking loading. The beam material satisfies with the co

A homogeneous free viscoelastic rod with constant cross-section is under the action of the follower force which has constant value is considered. It is well-known that for elastic rod the critical value of the follower force is approximately equal to

We study stability of the mechanical systems subjected to dissipative, gyroscopic, potential and non-conservative positional forces. We start from consideration of non-stationary system under the action of all forces, which are listed above in the ca

A method of extensive control based on a closed scheme is discussed, and the possibility of constructing a stabilizing momentum ensuring the asymptotic stability of the programmed motion of a spacecraft is proved.
