Gavryukov O. The scientific basis for developing tubular belt conveyors with variable transportation length

The dissertation deals with the development of the scientific basis for the theory of optimal design of tubular belt conveyors with variable length of transportation, their adaptation when creating new conveying, earth-moving and building machines. On the basis of studies the mathematical models for the following aspects were worked out: the process of a tubular belt loading during the change of a conveyor transportation length; transient process of conveyor belt deviation off the pulley with a slight curvilinearity of the generatrix; cargo holding capacity of a tubular belt when the transportation length is being changed; the impact of the cargo and conveyor parameters on the tubular belt durability, as well as on the cost of cargo transportation.
