Abstract
The article considers the problems of controlling the preliminary axial load on the ball-bearing support of a power gyroscope rotor by the frequency method. The study of the effect of the power gyroscope rotor rotation speed on the natural oscillation frequency under varying environmental conditions was performed on a special installation that combines a thermal, vacuum chambers and vibration installation using statistical methods for identifying and optimizing complex systems. The relationship between the natural frequency of the rotor forced oscillations and the speed of rotation, ambient temperature and pressure is identified in the form of a mathematical model, with the effect of each parameter under study being of nonlinear character. It is found that the effect of the rotation speed on the natural frequency of power gyroscope rotor oscillations changes significantly at different values of ambient temperature and pressure, and the value of the natural frequency is maximum at the static position of the rotor. The results of the study allow performing natural frequency technological control at different stages of instrument assembling under controlled conditions and can be used in the development of methods for controlling the frequency characteristics of inertial actuators of orientation and stabilization systems
