Olatunde, a: a Tensioner For The Belt-Driven Integrated Star

A Tensioner for the B-ISG System presents the and analysis of a Twin Tensioner for a Belt-driven Integrated Starter-Generator (B-ISG) system. The B- ISG is an emerging hybrid transmission closely resembling conventional serpentine belt drives. Models of the B-ISG system‘s geometric properties and dynamic and static states are derived and simulated. The objective is to reduce the magnitudes of static tension in the belt for the ISG-driving phase. A literature review of hybrid systems, serpentine belt drive modeling and automotive tensioners is included. A parametric study evaluates tensioner parameters with respect to their impact on static tensions. variables are selected from these for an optimization study. The optimization uses a genetic algorithm (GA) and a hybrid GA. Results of the optimization indicate that the optimal system contains spans with static tensions that are significantly lower in magnitude than that of the original . Implications of the research on future work are discussed in closing.
