The sufficient conditions for the existence of the integrating factor of a system of n differential equations of the rigid body dynamics, which allow n – 3 first integrals and one invariant relation or n – 4 first integrals ...

The mathematical substantiation of decreasing the influence of vibrations of a tested object on electrodynamic and electromagnetic benches is given. The structural schemes of benches with compensating feedbacks are shown.

The theory of the elastic interaction of the suspension of a gyroscope with an external wave perturbation under an arbitrary geometry of the meridian line form is constructed. The ways to compensate this influence with ...
