COMPACT ROTARY PLATFORM AS A UNIVERSAL LABORATORY STAND

Abstract

A single axis rotary platform is distinguished among the laboratory equipment for testing gyroscopic devices and systems and their sensitive elements. An overview of the design principles of industrially developed stands for the study of static and dynamic characteristics of gyroscopic devices and systems is provided. The scheme of design of the universal laboratory stand is suggested as the compact rotary platform for research of static and dynamic characteristics of micromechanical gyroscopes and accelerometers as sensors of angular speed. The physical components of such a stand and technical and technological problems of its practical implementation are reviewed. The proposed laboratory stand is considered as a cyberphysical system where computing components play a crucial role in determining the parameters of the system and the studied micromechanical sensors. For this purpose, in addition to the physical control loop of the electric drive to ensure the stability of the angular velocity of the platform, an independent measuring loop is considered for analytical determination of system parameters, including the studied micromechanical sensors. The versatility of the stand is ensured by solving the inverse problems, namely determining in the process of testing static and dynamic characteristics of the electric drive and measuring sensors that work on various physical principles. It is assumed that, in addition to solving practical problems of micromechanical sensors in the development of the appropriate information interface of the virtual device, a compact laboratory stand can be effectively used in the educational process during laboratory work in relevant disciplines of instrument making direction.
