Use of the linear electrodynamic actuator for the research of shock interaction of materials

The research of shock interaction is of paramount importance for solving problems of theoretical orientation (study of the internal processes impact processes, the study of physical and mechanical properties of materials under dynamic loading) and practical, applied orientation (improving the reliability and efficiency of machine parts, the use of shock interaction in various processes of surface plastic deformation, hardening, marking, etc.). These studies are relevant and always in demand in mechanical engineering, especially in aircraft, rocket building, engine building, automotive industry, etc. The work is devoted to the study of shock interaction, using the research of stand drums on the basis of the linear electrodynamic actuator. The aim of this work is to assess the possibility of using linear actuators, because of their design features and modes of operation, the study of different shock processes. The comparative analysis of various impact devices (hydraulic, pneumatic, electric) discusses the advantages and features of the linear electrodynamic actuator, the mathematical model of the dynamics of the actuator in the shock regime. The results of mathematical modeling of the dynamics of working for different sizes of the linear electrodynamic actuator showed good agreement with the data of actual samples. The variant of use of research stand as a calibrator shock and vibration - electrodynamic calibrator is shown, its scheme is given, especially the calculation of the calibration method of the strike, the main technological and structural parameters and the results of experiments for calibration of the vibration sensor, which allows, after appropriate modernization, and configuration, use of electrodynamic calibrator in Metrology are shown
