MODELING OF THE NONLINEAR SYSTEM OF DAMPING AND DAMPING OF A STRAPLESS INERTIAL MEASURING DEVICE

The purpose of the work being carried out is to develop a system of shock absorption and damping of a strapless inertial measuring device for space purposes that is vibration-resistant at all flight levels, including non-standard ones. In this paper, the further development of the concept of a linear system of depreciation and damping is considered. The nonlinear mathematical model of the dynamic system was developed in the Simulink environment, the parameters of the damping system were set and the simulation was run through a script in Matlab. A cycle of launches was carried out with iterative setting of the parameters of the damping system using only one type of dissipative forces. As a result, it was found that the option with only one type of vibration damping is ineffective. A mathematical model was launched that takes into account all types of dissipative forces at once. The key result of the work at this stage is a mathematical description of the ongoing mechanical processes and the formation of a group of solutions that provide the specified requirements for vibration resistance and dimensions of the shock absorption and damping system in the device. In future works, it is planned to refine the mathematical model in terms of the kinematics of the device being developed and conduct modeling to form the final concept of the depreciation and damping system.
