The Lock-up clutch of a torque converter directly transmits the engine power to the transmission in order to achieve a more fuel economy. Damper spring, a core part of lock-up system, makes the powertrain system stabilized by reducing the fluctuation torque of any engine system when lock-up clutch is operated. In addition, this part helps the improvement of total vehicle systems by increasing spring characteristics in aspects of the design facilities. This paper is to be used to determine basic materials for the damper system spring to study the main factors by comparative analysis of hysteresis of two different spring stiffness of damper system.
