Koval Y. Substantiation of parameters and modes of operation vibration search stumps

Work is devoted to researching of process of interaction of working body of search with root in the soil and optimization parameters working body and mode of application of force. On the basis of being technologies it is offered constructive circuit search, which works by the periodical influence of force. For ensuring frequency, oil moves to periodically. Analytical researches allowed to determine rational parameters working body and modes of their work taking into account physic and mechanical properties roots. Researches confirmed with experiment carrying out calculations. Work check and economic calculation proved rationality of application the developed stump search. On the basis of results of researches, offered to recommendation on the by determination of geometrical parameters grab, the modes of application of force to a stub root are defined, it is offered to give periodically oil in hydraulic cylinders, that are protected by patents of Ukraine for useful model.
