DORIN BADOIU RESEARCH CONCERNING THE USE OF POLYNOMIAL FUNCTIONS IN THE STUDY OF THE CONVENTIONAL SUCKER ROD PUMPING UNITS The analysis of the conventional sucker rod pumping units and especially their dynamics is laborious and requires a large amount of calculations due to the constructive complexity of the component structural elements. Therefore, expressing in a simplified but sufficiently precise form the various cinematic and dynamic parameters that characterize the proper functioning of the pumping units is extremely useful in analyzing the possibilities of their functional optimization. In the paper are presented a series of results concerning the expressing of some cinematic and dynamic parameters using polynomial functions in the case of the mechanism of a C-640D-305-120 pumping unit. The simulations have been performed with a computer program developed by the author using Maple programming environment. Experimental records processing was performed with the program Total Well Management.
