Frequency analysis of the shaft of the electromechanical drive of the small mobile robot

Problem statement and the research purpose. The implementation use of mobile robots in most diverse spheres human activity is currently an urgent task. At same time, ensuring their reliable operation functioning determines effectiveness to a certain extent. Using appropriate calculations during designing process various machines, particular robots, it possible increase reliability reduce material consumption developed machine prototypes, therefore cost its production maintenance. Methodology study. For small robot with electromechanical transmission, number were carried out according methodology. latter contains geometric, kinematic, dynamic, energy, technical economic calculations, strength rigidity analysis, modal analysis resonance frequencies oscillations workpiece being designed. Results investigations. On basis kinematic diagram robot’s solid-state model traction (driving) sprocket shaft crawler (track-type, caterpillar) drive was developed, for which necessary safety assurance factor determined on schematized (linearized) Serensen-Kinasoshvili critical stresses. Scientific novelty. article presents example designed transmission oscillations. It established that dangerous resonant are equal 11 Hz, 170 914 Hz. Practical value results. technique can be effectively implemented while new experimental industrial prototypes robots. Scopes further investigations subject paper. Further focused development complex methodology calculating drives taking into account calculations.
