ESTIMATION OF EFFICIENCY OF APPLICATION OF SYSTEM RECOVERY OF ENERGY IN CAR SUSPENDER

abstract 0761202041 issue 76 pp. 476 – 490 29.02.2012 ru 1704
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

EVALUATION OF THE QUALITY OF PLASMA COATINGS SPRAYED BY THE COMBINED METHOD WITH RUNNING-ROLLER OBTAINED THROUGH COMPUTER SIMULATION

abstract 0871303030 issue 87 pp. 383 – 395 30.03.2013 ru 1404
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

INCREASE IN EFFICIENCY OF A FOREST CAR BY MEANS OF A RECUPERATIVE HYDRAULIC ACTUATOR

abstract 1311707010 issue 131 pp. 100 – 113 29.09.2017 ru 488
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
