Abstract
All countries regulate CO2 emissions, triggering similar evolution on powertrain at a similar pace all over the planet. Engine irregularities are more severe due to downsizing and uptorquing. Torsional filtration targets are also challenging powertrain performance. This drives powertrain market and more efficient torque transfer system. Conventional filtration solutions such as clutch/dampers and DMF have their own limitations. For the past few years the addtion of centrifugal pendulum absorber meets the required filtration target. The vehicle architecture and type of damper accompanying pendulum absorber contribute to the dynamic stability and performance. In this study, we have shown the behaviors of DMF pendulum in rear wheel driveline with six speed manual transmission. Normally the performance of a pendulum in high engine speed range is not so efficient compare to lower speed range. This study mainly focuses on variations on design parameters of pendulum, which enables better filtration in high speed range.
