The warping ratio of slope and intercept of experiential equation between actuating voltage and corresponding stepping motion displacement is 1.80/0 and 9.070/0 respectively, and it is shown that the actuator has good motion stability.
As for the vortex line located in the centric line of water tunnel, its stability of motion is analysed in detail and the conclusion is that it can be always kept at the centric line of water tunnel for any different wavenumber purturbation except zero wavenumber.
Criteria for the nonlinear dynamic stability of rotative vehicles are derived by the Liapunov′s first method and the Routh-Hurwitz stability criterion,this criteria can be applied to the dynamic stability analysis of controlled rotative missiles,projectiles and rockets.
The self-synchronism and stability of the double excitations for nonlinear torsionalvibration system of single-degree-of-freedom has been studied theoretically in the reso-nance region, from which the effect of nonlinear character on self-synchronism and con-dition of motional stability have been obtained for the torsional vibration.
A new notion of computed stability of motion that does not assume exact realization of this motion in the systems under study is introduced.
Relative stability of motion of a body with a conical cavity containing an ideal liquid
The stability of motion corresponding to the exact solution is proved relative to arbitrary perturbations in the cavity shape.
The stability of motion of giant planets on cosmogonic time scales was established by numerical and analytical methods, but the question about the evolution of orbits of terrestrial planets and arbitrary solar-type planetary systems remained open.
Stability of motion of a solid in the Steklov's case
The perspectives of investigations on the problem of integrity and development of the principle of dynamic stability in contemporary evolutionary biology as integrating factors are discussed.
Dynamic stability of lattice blades with slight mismatch of natural frequencies
A numerical experiment has been carried out to determine the decisive factor in the loss of dynamic stability by a cone with a circular conical stabilizer.
Investigation of Dynamic Stability Regimes for Axisymmetric Bodies in Supersonic Flow
Emphasis is placed on the determination of the trimming angles of attack for different positions of the center of rotation and the static and dynamic stability coefficients (the model oscillation damping coefficient).
