The stringent worldwide CO2 limit values are the primary requirement for future mobility. So the environmentally vehicle’s drivetrain is element of energy efficiency worldwide mobility. Hence, the development of efficient drivetrain is the top priority. We can also follow the optimization of existing system and introduction of completely new system. According to the various experts, these new trends have expressive effect on torsional vibration in drivetrain. For this reason, many elements such as the clutch disc equipped with a torsional vibration dampers and dual mass flywheels are posed higher and higher requirements for minimizing vibration, and that, in the case of research of mentioned elements are required the application of methods of design diagnostics. In order to accomplish the growing requirements we need to know the basic dynamic properties, torsional stiffness and damping.Therefore, we decided to study of these properties of a dual mass flywheel in our laboratory. Mentioned properties were evaluated from measurements on the experimental stand for measuring by forced vibration and they were monitored at various conditions.
