 Abstract
In this paper are presented some results concerning the optimum choice of the dimensions of the component elements of the mechanism of the sucker rod pumping units with conventional type geometry when it is imposed the reduction with a certain percentage of the extreme values of the acceleration at the polished rod. The optimization problem is solved by considering unchanged the value of the stroke of the pumping unit. A simulation computer program that uses the Optimization package in Maple program has been developed. Some simulation results obtained in the case of a C-640D-365-144 pumping unit are presented.

 Rezumat
In articol sunt prezentate o serie de rezultate privind alegerea optimă a dimensiunilor elementelor componente ale mecanismului unităţilor de pompare cu prăjini cu geometrie convenţională când se impune reducerea cu un anumit procent a valorilor extreme ale acceleraţiei la prăjina lustruită. Problema de optimizare este rezolvată considerând nemodificată valoarea cursei unităţii de pompare. A fost realizat un program de calculator care utilizează pachetul Optimization din programul Maple. Sunt prezentate o serie de rezultate ale simulărilor obţinute în cazul unei unităţi de pompare C-640D-365-144
