Dr. John Starkey is an Associate Professor of Mechanical Engineering at PurdueUniversity. He received his B.S. and M.S. from The Ohio State University and Ph.D.from Michigan State University. Dr. Starkey was awarded the Harry L. Solberg Awardin 2006 and 2010, which is awarded to an outstanding teacher by the Purdue Schoolof Mechanical Engineering and selected by it student body for excellence in teaching.His research interests include acoustics and noise control, design, vehicle dynamics,structural dynamic modification, vibrations, and model testing.
Continuously variable transmissions (CVTs) have been shown to improve fueleconomy between 5 and 10 percent when compared to conventional transmissionswith planetary gears. CVTs have become more popular in recent years due todevelopments in hybrid vehicles and rising fossil fuel prices.
The CVT market is dominated by transmissions where the shift profile is adjusted bymechanical means such as flyweights, springs, and hydraulics. Researchers at PurdueUniversity have developed a novel system that fully integrates the adjustmentactuator within the CVT. This technology allows the shift profile to be adjustedelectronically using software changes, which has several advantages over currentelectronic continuously variable transmission (ECVT) technology, including reductionsin the cost of the CVT motor assembly, in the number of moving parts, in theproliferation of overall hardware, and in the time to market of the product.
Advantages:-Reduced load on the electrical system when changing gear ratios-Reduction in size compared to mechanically actuated CVTs-Increased reliability through a reduction in the number of moving parts-Reduced time to market when engineering specific applications
