AUTOMOTIVE SHOCK ABSORBERS’ APPLICABILITY FOR DAMPING RESONANT OSCILLATIONS IN CONSTRUCTION MACHINES

Introduction: Many vibration transport and technological machines (VTTM) such as conveyors, screens, crushers, etc. operate in a high-frequency mode, or above resonance. Resonance occurs during machine start slowdown, resulting sharply rising values of the amplitude velocity oscillations. affects VTTMs adversely due to increased dynamic loads reducing machinery operating life reliability causing noise. Purpose study: We aim provide theoretical substantiation for possibility apply automotive shock absorbers VTTM oscillatory process control develop an example practical implementation device. Methods: The method controlling processes lies use dual-mode absorbers. In offer minimum resistance motion. resonance increases, therefore, decreases predetermined value. Results: simulate order determine characteristics damping device, which ensures suppression resonant oscillations but does not affect process. propose new technical device implementing required oscillation characteristics. is made form hydro-pneumatic absorber, similar terms design. Such design makes it possible slight machine’s useful (operating) vibration, but, at same time, increases significantly case amplitudes. originality our study development type hydraulic utility model patent has been obtained. scientific novelty mathematical description with software analysis according developed model, results computer simulation absorber operation.
