Abstract. The performed study contributes to the optimization of some functional aspects of sliding electric contacts, by means of a program of experimental proofing, to achieve a working improvement, from tribological and electrical point of view. Achieving this task has necessitate the design and construction of proofing stands, equipped for measuring operations and automated processing of information, for adjustment and control of the main parameters that intervene under these circumstances in working conditions. The experimental equipment has been conceived, to cover the entire value field, according to the program established for the main parameters: the interaction force on the contact level, implicit the medium pressure, the relative velocity (controlled in a very wide field of values), the electric sliding contact solicitation, by modifying widely the current density.

EKSPERIMENTALNI DOPRINOSI O UTICAJU PRITISKA NA ELEKTRIČNE PARAMETRE KLIZEĆIH ELEKTROKONTAKTA
Ovaj rad doprinosi optimizaciji nekih funkcionalnih aspekata kliznih električnih kontakta, pomoću eksperimentalnog istraživanja kako bi se ostvarilo funkcionalno poboljšanje sa tribološkog i električnog aspekta. Da bi se ostvario ovaj zadatak neophodna je izgradnja ispitnih štandova opremljenih za merenja i automatsku obradu podataka, za podešavanje i upravljanje glavnim parametrima koji utiču na radne uslove. Eksperimentalna oprema je dizajnirana tako da pokrije cele merne opsege glavnih procesnih parametara: sila interakcije na kontaktu, implicitni pritisak medijuma, relativna brzina itd.
