Model of a microgravity platform based on the mechanical principle of operation

Abstract

The paper considers a model of a mechanical microgravity platform. The purpose of the paper is to develop a model of a mechanical microgravity platform. The experience of creating small spacecraft for technological purposes for carrying out gravity-sensitive processes on board is analyzed. The principle of operation of a mechanical microgravity platform is described. The microgravity platform is equipped with an electrodynamic drive to compensate for micro-accelerations. The electrodynamic drive have three identical independent control circuits to compensate for microaccelerations along the three corresponding coordinate axes. The second Kirchhoff rule was used to describe the current strength in the closed circuit of the drive. Dynamic Euler equations were used to develop the control laws. The equations for estimating micro-accelerations inside the protected zone are obtained. The ways of meeting the requirements for microaccelerations for the implementation of gravity-sensitive processes on a spacecraft are shown. Recommendations are given on the use of the platform on board a small spacecraft for technological purposes.
