Abstract

Problem Statement (Relevance). The aim of the research is to identify the possibility of designing a rotator with the fixed rate of free rotation. Methods Applied. To stabilize angular velocity, it is required that changes in angular momentum result in relevant changes in moment of inertia. To settle this issue, a device was synthesized. Such device is reasonably called a stabilized rotator. To identify the nature of behavior of the stabilized rotator in various modes (kinematics, dynamics), it is analyzed. Synthesis and analysis of the stabilized rotator are performed using the balance between theoretical mechanics and formal and identical transformations. Originality. The natural rotation frequency of a stabilized rotator is strictly fixed (it does not depend on either moment of inertia or angular momentum) and remarkably coincides with the natural oscillation frequency of the pendulum with identical parameters. When the angular momentum changes, the radius and tangential velocity change (the rotation frequency does not change and is equal to its own). Result. At zero torque in the stationary mode, the rotation frequency of the stabilized rotator cannot be arbitrary and takes on a single value. Just as the frequency does not coincide with the natural frequency during forced oscillations of the pendulum, the rotation frequency of a stabilized rotator under loading does not coincide with the natural rotation frequency. Practical Relevance. A stabilized rotator can be used to control the natural frequency of a radial oscillator, although in this function it may have strong competition with mechatronic systems. On the contrary, as a rotation stabilizer, its competitive capabilities are undeniable and determined by the extreme simplicity of the design.
