Abstract
When studying the electrical on-board system of the vehicle as a whole, it is necessary to consider the dynamic characteristics of all its components. One of the links of the system is considered - a mechanical variator for stabilizing the frequency of rotation of the generator rotor. When the generator is driven by an aircraft engine, there are factors that prevent its stable operation. The rotation frequency of the drive motor is constantly changing, so there is a problem related to the creation of a high-quality system of mechanical stabilization of the rotation frequency. Possible methods of stabilizing the frequency of rotation of the electric generator rotor by using stepless variators are considered. When analyzing the possible types of stepless variable speed variators, mechanical variators were chosen, which have a number of advantages over other types, such as their compactness, low cost, high efficiency, etc. In particular, it is proposed to use differential gear mechanisms of various schemes as stabilizers: a differential variator made using schemes IA and AI, as well as a differential mechanism AI with a free carrier. As devices that provide self-regulation of the output rotation frequency, it is proposed to use speed regulators, the principle of operation of which is based on the use of centrifugal force, which changes when the rotation frequency changes at the input to the variator. A concrete example for a differential mechanism (AI) shows how to perform kinematic and force calculations to ensure constancy of the output speed when the input speed changes within ± 6%.
