Project aim is experimental research of hydro-dynamic effects which appear at work of liquid auto-balancing units on rotors with horizontal axis of rotation. Experimental research was conducted by using methods for speed video-shooting and dynamic photo-shooting. Obtained results were processed by modern computer technologies. Accomplishment of the project involved using vibration measuring instrumentation to measure and gather vibrations, stand for experimental research, transparent cylindrical chambers, video-camera for shooting motion of the liquid in ABU. The project accomplishments include experimental research of stationary and non-stationary vibrations of the rotors with liquid balancers set on them while appearing hydro-dynamic effects exactly on rotors with horizontal axis of rotation and variable imbalance. It has been completed analysis of auto-balancers on the base of numerical experimental research of their applying to variety of machines with vertical and inclined rotor rotation axis. It has been researched the possibility for auto-balancing car wheels by partial filling them with liquid. The speed video-shooting has been conducted in special chamber ABU made from optically transparent material on the base of which it was created a video-frame allowing to observe behavior of the liquid being in closed cylindrical chamber during rotating on rotors with horizontal axis of rotation. The conducted research has first resulted in analytical dependence of automatic balancing effectiveness on parameters of rotor-ABU-liquid system that allows to develop mathematical tool to design ABU with liquid working bodies. Project results have been implemented in LTD "AK" "ADVIS" to reduce vibrations of industrial ventilator and in educational process of Khmel'nyts'ky National University. These results can also be used for balancing rotor machines with horizontal axis of rotation in enterprises of light and food industry, machine engineering, medicine to balance separators and barrels of domestic washing machines with horizontal barrels.
