Fuzzy-Based Evaluation of a Specific Drive Train

This paper introduces a fuzzy-based evaluation method of a specific portion of the power train. In this case study was evaluated a specific combination of a commercial high-performance tractor engine and power split hydrostatic infinitely variable transmission (IVT). The first part of the study describes the field test of the power train, then the mathematical model of this power train is introduced. The objective of this study was the evaluation of the power train in some specific phases. The tractor is one of the most important machines in the agricultural mechanization and the mostly used tractor speed ranges were generated by different engine speed and transmission ratio combinations. In each case the engine consumption and the transmission efficiency were calculated based on this mathematical model. These results were evaluated with the method of corrected fuzzy mean (CFM). All of these calculations were performed in MATLAB. This study gives a design guide for the future processes of the engine-transmission matching as a result.
