MODELLING TECHNIQUE OF THE MOUNTING MECHANISMS PLATE OF FOREST SOIL-TILLING IMPLEMENT
Description
The 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

Description
On the base of the smoothed particles hydrodynamics method, the mathematical model of plasma coating process on details surfaces in the mode of electrical parameters modulation is performed. This model al-lowed optimizing the plasma coating process parame-ters
-
Description
The reasons of a weak inearthing of spherical disk working bodies of soil-tilling tools are considered. The analysis of shortcomings of existing ways of forced deepening of disks is carried out. Three new schemes of devices to designs of hinged mechanisms of a tractor are submitted

Description
On the basis of one of the discrete methods (Smoothed Particles Hydrodynamics Method) a mathematical model of the combined hardening of surface details was developed. The model allows optimizing the processes of plasma spraying, me-chanical, electro-mechanical processing

ESTIMATION OF EFFICIENCY OF APPLICATION OF SYSTEM RECOVERY OF ENERGY IN CAR SUSPENDER
Description
Results of probes of systems recovery in suspenders of cars are presented. Designs of devices recovery energy for use in suspenders of cars which specify in their per-spective use in a direction of increase of efficiency of cars are developed and approved under operating condi-tions

INCREASE IN EFFICIENCY OF A FOREST CAR BY MEANS OF A RECUPERATIVE HYDRAULIC ACTUATOR
Description
In the article we consider severe conditions of operation of forest cars caused by the difficult land relief and service dirt roads which are badly equipped, as a rule, abounding with roughnesses, obstacles in the form of large superficial roots, stones and boulders, frequent turning movements, steep ascents and descents, considerable cross biases, hollows and boggy sites which lead to increase in consumption of fuel by 1,5-2,0 times and to cutting-down of their life cycle. Ways of increase in their efficiency by equipment by the recuperative mechanisms providing reuse in working process unproductively disseminated to the environment energy, and also promoting increase in reliability and simplification of a design of such cars are analyzed. On the basis of the analysis of the results received when studying a condition of a question, the authors have offered a design of a forest car with a recuperative hydraulic actuator in which gears of recovery are the arrow, a handle and the basic and rotary device of the hydraulic manipulator, reversible hydraulic motors of wheels and a suspender of the forest car. The scheme is submitted and work of a recuperative hydraulic actuator is described. The technique of an assessment of efficiency of the offered design of the forest car with system of recovery of energy is given. The cyclogram of working process of the forest car with the offered hydraulic actuator is constructed
