    Improvement of structural diagrams of vibratory separators with electromagnetic drive
    (Видавництво Львівської політехніки, 2017-12-23) Korendiy, Vitaliy; Shenbor, Vladyslav; Shenbor, Yurii; Lviv Polytechnic National University
    The features of construction of structural schemes of vibratory separators based on vibratory conveyors with electromagnetic drive are considered. The structural diagram of the vibratory separator developed on the basis of three-mass oscillatory scheme with the possibility of transporting the mixture and the separated component by vibratory transportation in opposite directions is proposed, and the device operation is substantiated. The main criteria of separation efficiency are presented. The possible directions of effective implementation of vibratory separators are suggested.

    Ways of improvement of productiveness of vibratory tubular conveyors
    (Видавництво Львівської політехніки, 2017-12-23) Shenbor, Vladyslav; Korendiy, Vitaliy; Brusentsov, Volodymyr; Lviv Polytechnic National University
    The principle of construction of two-mass lengthy tubular conveyors of coaxial type with electromagnetic oscillations exciter is considered. The dependence for determination of the conveyor productiveness is substantiated. The design diagrams of tubular multi-tube conveyors of twoand three-mass vibratory schemes are proposed and the efficiency of their implementation in order to increase the productiveness of bulk and lump products feeding due to the use of all tubular elements as transporting ones is substantiated.

    Substantiation of usage expediency and analysis of exploitation problems of low-power wind turbines
    (Lviv Polytechnic Publishing House, 2015) Korendiy, Vitaliy; Vergeles, Vitaliy; Lviv Polytechnic National University
    Wind energy is considered as one of the most perspective, developed and ecologically clean energy resource. Nevertheless, it is associated with several harmful factors which influence environment. That’s why basic causes and zones of vibration initiation in wind turbines, as well as negative vibratory and acoustic factors of wind turbine influence on natural beings, are analyzed. In conclusion it is substantiated that the ecological problems of low-power wind turbines may be neglected and they should be widely used for economic development and energy independence improvement of our country.

    Mobile robotic systems with walking movers and mechanisms of orientation
    (Lviv Polytechnic Publishing House, 2015) Korendiy, Vitaliy; Bushko, Oleksandr; Denderys, Nazar; Lviv Polytechnic National University
    The expediency and areas of use of walking machines are substantiated. Three simplest diagrams of cyclic (lever) walking mechanisms (four-link, four-link with possibility of changing the position of the rocker arm rotation axis, six-link) are considered. Principal diagram of the lever mechanism of orientation of walking module with two cyclic movers is propounded and its operating features are analyzed.

    Combined mechanical systems of anti-storm protection of horizontal-axis wind turbines
    (Lviv Polytechnic Publishing House, 2015) Korendiy, Vitaliy; Vergeles, Vitaliy; Lviv Polytechnic National University
    The necessity of further improving of existent regulation mechanisms is motivated for the purpose of increasing of accuracy of power regulation, effectiveness and reliability of wind turbines functioning in wide range of wind speeds. The prospects of creation of combined mechanical systems are considered, where the possibilities of simultaneous blades turning and folding, blades turning (or folding) and wind-wheel deflection out of wind direction are provided.
