DOMESTICALLY PRODUCED GRAIN HARVESTERS: PRIMARY TENDENCIES OF DEVELOPMENT
The fundamental demands to perspective grain harvesters of the fifth generation distinguished with broad application of the automation means are considered. It is shown that the employment of complex board informational-controlling system including the electronic control and diagnostics of engine and main harvester aggregates, allows considerably to increase its service life and essentially to boost the working efficiency. The computer simulation of harvester perspective models has allowed reducing design period from 45 down to 30 months. With the purposes of high quality achievement the necessity of development of a standardized procedure of rational control by reliability at the all stages of harvester life cycle is expressed.

MODERN LEVEL AND FUTURE TRENDS FOR USE IN REPUBLIC OF BELARUS TRANSPORT FORCES MULTIFUNCTION MACHINES.
The modern level of multifunction machines on combined rail-wheel motion and its future trends for use in Republic of Belarus transport forces and national economy enterprises has been considered. The constructions of combined rail-wheel motion mechanisms and characteristic of the chassis for their aggregation has been analysed. The possibility of creation on the chassis MAZ-630308 and Ø-406 «Belarus» with combined rail-wheel motion the power-hungry bearer of different equipment for the support and repair automobile and railway roads and its using as locomobile has been showed. Single has been viewed different variants of enlargement the technological possibilities of the combined rail-wheel motion machines by mounting various plug-in work equipment, mechanisms and systems which can raise the level of safety, mechanisation and automation of work.

INVESTIGATION PERSPECTIVES OF DYNAMICS OF TANK VEHICLES FOR LIQUID LOADS
It is analysed a current state and investigation perspectives of dynamics truck and rail tank vehicles. There are resulted equations presenting movement of considered system members. The equations of continuum mechanics for the description of liquid movement, and the dynamic equations of mechanics of rigid body for vehicle structure are used. There are evaluated problem solvings about rolling stability of tank cars, about optimization of tank shape, and also about effect of damping baffle on the kinematic and dynamic parameters of tank vehicle movement by means of the examined equations.

DEVELOPMENT OF ELEMENTS OF THE ROLLING STOCK CONSTRUCTIONS FOR LIQUID AND GRANULAR CARGOES TRANSPORTATION
Pressing questions on the further perfection of elements of designs of a used railway rolling stock are reflected. The complex of the offered technical decisions is based on spent in the Belarus state university of transport researches in the field of an estimation of durability of elements of designs of freight cars in view of features loading them transporting by liquid and loose cargoes. Novelty and utility of design development proves to be true patents of Belarus for useful models and their use at manufacturing new and modernizations of existing elements of designs of a cargo rolling stock.

SELF-SIMILARITY AND WAVE PROPERTIES OF PLASTIC DEFORMATION UNDER IMPACT LOADING AS A RESULT OF KINETIC TRANSMISSIONS IN MICROSHEAR SYSTEMS
This paper offers the description of self – similarity and wave character of plastic deformation under high speed impact which is the result of kinetic transition in the system of microshears. It is shown that plugging has a self-similar character due to kinetic peculiarities of microshear accumulation. Propagation of plastic shear instability bands as specific waves of plastic deformation with distinguishing features of solitary waves has been modeled numerically in the framework of the examined model.

CONTACT INTERACTION OF FACE OF THE CRACK AT THE BEND OF THE STRIP OF VARIABLE THICKNESS
The problem of mechanics of contact interaction of face of a crack for strips (beams) of variable thickness when the strip is bent in the plane under action of the set system of external loadings (the constant bending moments, in evenly distributed pressure or the point forces) are considered. Thickness of a strip is considered a variable. Definition of contact stress in each approximation come to the solution singular the integrated equation.

ON DETONABILITY LIMITS OF GAS DETONATION IN TUBES
The near-limit propagation of spinning detonations in 3.5% C2H2+26,5% O2+70% ArAr mixture have been carefully studied in tubes of 25.3 and 50 mm in diameters. Quantitative criteria governing the limits of stable, unstable, and low-velocity detonations have been suggested on the basis of detailed reaction flow measurements in induction zone of decaying detonations. The proposed relationships link ignition time corresponding to stagnation temperature and pressure of the gas behind the leading shock front, shock wave velocity and radius of the tube.
