Romanovych Y. The perfection of technical means for the cleaning of the semi-wagons from the remainders of loose bulky materials.

The work is containing investigations of the process of the vibration cleaning of railway semi-wagons from remainders of loose bulky materials. The analysis of existing types of cleaning devices presented in the work has proved that supported vibration cleaning devices of lateral action are most efficient. The following investigations were held: influence of the place of mounting of the vibration cleaning device on the semi-wagon, the influence of sliding of the body of a semi-wagon on the spring beams of bogies, the influence of oscillation of lids of the unloading hatches on the cleaning effectiveness of semi-wagons from remainders of loose bulky materials. The corresponding methods of the oscillating process of the body of a semi-wagon during lateral vibration cleaning were worked out and the truth of the methods was proved experimentally. The new methods of determining of the main parameters of vibration cleaning devices with the possibility of analytical verification of the strength of a semi-wago n. On the basis of the theoretical and experimental investigations the new construction of the supported vibration cleaning device of lateral action was worked out. Key words: semi-wagons, vibration, cleaning, loose bulky material, vibrating device, effectiveness.
