ANALYSIS OF DYNAMIC REGIME OF A HEAVY MACHINE FOR SUPPLEMENTARY POWER CONSUMPTION EVALUATION.

In this paper the author proposed some indicators for performance evaluation in dynamic steady of working time in the case of heavy machines. Thus, it was monitored the hydraulic parameters of a wheel loader knowing it’s as a machine with an intense and varied working regime characterized by over-pressurization occurred because of excessive loads that appear when execution different tasks during technological cycle on construction site. Based on hydraulic parameters, it were evaluated engine power required for loading phase and, taking into account by the performance indicators, the supplementary power needed for task execution.
