Воrys M. Substantiation of Trailing Vehicle Parameters for the Improvement of its Performance

The object is a process of transporting wood by means of transport-skider wheel tractor. The aim of this work is to make the conformity with the law influence of substantiation of wood transport wheel on their performance that will increase un efficacy using of timber machines. Thereare some methods of investigation: a theory of oscillations and stationary accidental processes, the mathematical modeling, the numerical methods, mathematical experiment design and mathematical statistics. Novelty: at first the generalized mathematical model of oscillations wood transport wheel has been developed; the middling parameters macroprofile and a plan of mountainous wood track has been determined; the parameters of the trailing transport wheel withe it’s oscillations in the transmission and of oscillations in vertical longitudinal plane; the regression models for the mathematical analysis of the effect of the parameters of timber-hauling vehicle on the indicator of smooth movement and adhesive dynamics have beenreceived. As a result it is received the regression dependences of the effect of the composition parameters on the indicators of the wheel machine’s performance. The level of introduction: the positions and practic recommendations for the uses in the industrial conditions are elaborated in the work; a wood transport machine in bathed of wheel tractor is elaborated and used for exploitation. Area of use – forest stoking up, for the wood transport and also – in scientific researches and educational process.
