METHODOLOGY OF THE DESIGN CALCULATION OF THE ELECTRO-HYDRAULIC SERVO DRIVE OF TECHNOLOGICAL EQUIPMENT

Machine-building industries and enterprises for modernization of railway rolling stock are constantly increasing the requirements technical functional characteristics technological equipment drives. The improvement drives ensures implementation optimal laws working bodies motion, accuracy regulation their movementsand stability speeds under variable load conditions, that has a direct impact on quality products productivity.The use automatic equipment, in particular electrohydraulic servo drives, achievement arbitrary kinematics body possibility software its motion. development high-performance specialized is rather labor-intensive process requires engineering methods project calculation make it possible to evaluate main parameters, select drive elements devices, predict static dynamic characteristics.Currently, there separate procedures designing electro-hydraulic various mechanical processing, processing materials by pressure, metal-cut-ting machine tools systems, tool etc. available not universal, as rule they focused different classes both conventional initial data, apply and, result, have incompatible results.The continuous modern machine-building railways creation generally accepted equipment. Based works authors design mathematical modeling research characteristics, well correction ofregulation, unified method proposed.The work devoted an methodology with throttle adjustment which makes characteristics.An control tech-nological repair presented. application involves setting following data: maximum (force); tracking speed without load; error (or allowable at speed); piston stroke; mass moving elements. According calculations made order: scheme, selection fluid nominal pressure; parameters hydraulic cylinder; choice amplifier; determination feedbackparameters, factor transmission coefficient electrical unit; assessment characteristics; linear model; durability assessment; study regulation; correction. An example pressure force 160 kN 0,05 m/s given. results using MATLAB package presented.An proposed.
