• Rotation of the cylinder in the flo­wing stream

  The features of modeling the dynamics of the rotational movement of a cy­lindrical rod in a homogeneous flow of a viscous liquid are considered. The angle of attack, the angle of rotation, and the angular velocity of the rod are studied numerically. The results of solving the boundary value problem ...

• Distribution of NQR relaxation times in the rotating frame of reference in micro-sized crystallites

  This article presents the results of an experimental study into the effect of powder crystallite size on spin-lattice relaxation times in a rotating frame for 35Cl NQR in potassium chlorate, as well as the nutation interferograms. To obtain the distribution of relaxation times, a multi-exponential decay inversion of the longitudinal component of the nuclear magnetization in a rotating frame ...

• Dynamics of a cargo lift system

  A device for lifting of a cargo is modeled by a mechanical system with three degrees of freedom. With the increase in the weight of the load is reduced the steady-state rotation speed of the drum, the settling time varies slightly. The calculation of the oscillation frequency of the cable relative to the vertical. It is established that change of the angular velocity deviations correspond to oscillations of mathematical ...

• Dynamics of falling rotating particle. Part 2

  It is established that the increase in initial vertical speed of particles leads to growth of deviation of trajectory of particles from vertical. Thus particles reach surface because of bigger vertical speed on initial site of trajectory that is confirmed by schedules quicker. 1. Яценко В. П., Наумов В. А., Соломенко А. Д.
