Description
In this article we have considered the issues of forming a complex system of models of VADS (driver - vehicle - road - environment) in terms of the intensity of traffic on them. We have proposed the two-level model of governance system in DU-TP, which includes strategic and operational (current) management. The algorithm for management of this system including the movement of vehicles in different natural and climatic conditions, providing normative and actual parameters of the road has been studied. We also offer several levels of management exploitation of roads and traffic

MODELLING TECHNIQUE OF THE MOUNTING MECHANISMS PLATE OF FOREST SOIL-TILLING IMPLEMENT
DescriptionThe simulation of the physical and mathematical model of the mounting mechanisms of a forest soil-tilling implement is developed. The model allows, on the basis of computer experiments, to determine op-timum geometrical parameters of the mounting mechanism

THE METHOD OF TE IMPROVEMENT OF POWER AND ACOUSTIC PARAMETERS OF TAPE CONVEYORS ON A HOVERCRAFT
DescriptionThe method of control of the amount of flow area of the supply nozzles in tape conveyor on a hovercraft is considered in the article. The local system that implements the principle of direct action to control the thickness of the air cushion is shown. Based on the hydrodynamic model, the formula for the engineering calculations of values of the moving devices are determined

Description
The mathematical model of heat and mass transfer during adsorption-contact drying of ceramic bricks within the framework of the mechanics of multiphase systems is constructed
-
Description
One-temperature limited version of the general model of adsorption-contact drying for the ceramic brick is considered. Numerical modeling of heat and mass transfer in the donor and the acceptor samples for one-dimensional approach is carried out. It is shown, in particular, that the moisture diffusion coefficient of material in the contact zone can vary significantly due to changes in the conditions for liquid-phase transfer

MATHEMATICAL MODELING OF THE WORKING PROCESS OF LEVER BREAKER
DescriptionThe dependences of the distribution of stump roots, allowing to model stump parameters to assess the difficulties of stumping are given, in requirements justification for stumping equipment. Based on the analysis of lever breaker working process, the differential equation of lever motion is got, which connects the moments acting on it and breaker performance modes and allows to set the parameters and modes of lever breaker in stumping of various sizes and species of wood

MATHEMATICAL DESIGN OF PROCESSES IN HYDRAULIC DRIVE SYSTEM OF FOREST MANIPULATORS
DescriptionDescription of hydro kinematic scheme of forest manipulator with additional damper connection is given in the article. Optimal damper parameters for manipulator dynamic loading decrease are defined on the basis of operation mathematical model solution

MATHEMATICAL MODELLING OF THE COMPRESSION PROCESS OF WOOD
DescriptionRheological model for wood mechanical behaviour, viewed as a medium with dual porosity, is considered. Mathematical modelling of compression process of a wooden sample in a special mould is done at stable temperature conditions with the help of numerical methods. It is shown, in particular, that the durability level of essentially depends on the rheological characteristics of the structural skeleton and the wooden substance, as well as on reallocating of fields of moisture and porosity
