Lеshchenko O. Methods that improve caterpillar mover by the adaptive set up of its chain.

The dissertation determines the dependence between chain tension and the geometrical parameters of some chain areas in caterpillar movers. The chain-drive is adaptive set up by automatic mechanisms in a dynamics. Three methods of changing chain tension are suggested in this work. The method of differential changing chain tension is first offered. A stand that is an imitator of differential changing of chain tension is developed. The mathematical model uses the physical processes of its work and is based on the methods offered before. The distinctive feature of all methods that was offered is that they take into account the partial piling of chain on all wheels. The cases of track assembly dynamics are investigated using the kinetostatics methods. Suggestions to use all-wheel drive electromechanical track-type vehicles are developed. Possibility of using electromechanical systems for adaptive set up of chain tension in a dynamics is shown in further developments of small caterpillar technique. Such technical decision allowed to raise a capacity of caterpillar mover.
