Titled "The Role of Mechanical Clutches in Dampening Torsional Vibrations," the piece describes how modern damper technology has evolved over the years to effectively reduce driveline resonance that is created naturally in any internal combustion engine. It also points out how modern dampers have been adapted to work especially well with today's high-torque, low-speed engines, which increase the amount of vibration in the drivetrain.
Prashant Kulkarni, engineering manager, Clutch Division, authored the paper and notes, "The damper is the most critical part of a clutch," he says. "If you design the stiffness of the damper appropriately, it will positively impact the entire driveline."
The paper includes information on how breadth of product, selecting the correct amount of friction material and the number of springs all factor into the success of a modern heavy-duty clutch. Kulkarni also presents an overview on how clutches have evolved over the years.
