Abstract
Improvement of the manufacturing technology for gyroscopic devices, which autonomously generate motion parameters of moving objects, has strategic importance and priority for various industries. The object of current research is a spherical rotor of an electrostatically suspended gyroscope which geometric parameters determine the accuracy characteristics of the device. The paper presents results of the process modeling of spherical form correction for rotors of electrostatically suspended gyroscopes at the stage of its manufacture during the coating deposition process. The proposed mathematical model of the deposition process is based on the placement of a movable screen with a hole between a rotor and a spray source. The axis of the hole lies on the dynamic axis of the rotor and it provides a formation of a spherical segment on the coating rotor surface. During deposition of an additional layer, the screen or rotor moves along the dynamic axis of the rotor changing the distance between the rotor and the screen, and there is additional rotation of the rotor around its dynamic axis. It allows adjusting the curvature of the formed coating on the rotor surface. An analytical model of the technological process for correcting the shape of spherical rotors of electrostatically suspended gyroscopes has been developed. A mathematical description, control factors and signifcant parameters of the process are given. The results of practical testing of the developed model are presented. The presented mathematical model makes it possible to correct the shape of the rotors during the deposition of a functional coating expanding the technological possibilities and increasing the accuracy of rotors.
