Systematic Modeling of a Steering Vehicle Differential Using Power-Oriented Graphs

This paper concerns the systematic modeling of a steering vehicle differential using power-oriented graphs. The proposed modeling provides two power-oriented block schemes: a full elastic one and a reduced-order rigid one, both allowing to effectively simulate the considered differential equipped with clutches. The proposed modeling procedure is fully systematic, following a step-by-step process and employing two algorithms for the calculation of the model matrices. The considered simulation scenario, which includes the locking and unlocking phases of the differential clutches, shows the good superposition between the results given by the full and reduced-order models.
