Summary: The method of defining of required power of induction motor for driving aggregate with variable load, velocity and inertia values is proposed. The scheme of rigid drive with ideal character of motor, having unlimited power is supposed as a design scheme. The selected motor is checked on overload capacity during speed up and stable motion. As example, the design of motor power for testing of cutting apparatus of mowing machine has been performed. It is shown, that using the spring loader in this drive gives the possibility to decrease the installed power of induction motor by 2.5 times.

Применение системного подхода к обоснованию динамической модели механических передач. pp. 58--63
Summary: The paper deals with the application of system approach aspects to the study of gear dynamics. It has been shown that the transfer function is not constant and depends not only on the intrinsic properties of the gear but on the performanse of a higher order system including the gear itself. On the basis of the experimental research done with a computer-aided system, dependences proving theoretical assumptions were revealed. A dynamic model taking into account presence or absence of the gear selfbreaking is described in the paper.

The rise of viscosity above its initial value and the scatter of the data for various volunteers is observed at 40 °C. The dependencies of the relative changes of the viscosity on the heating time at 41 and 43 °C are almost the same.
