Lock-up clutch of a torque converter in an automatic transmission directly transmis the engine power to the transmission in order to achieve a more fuel economy. Damper spring, a core part of lock-up clutch system, makes the powertrain system stabilized by reducing the fluctuation torque of any engine system when lock-up clutch is operated. To analysis stress concentration when the torque converter’s damper spring operates, simulation has been carried out by using DAFUL, a dynamic analysis commercial code. As a result, when the damper operates, can analysis spring’s stress distribution and spot of the maximum stress. Furthermore, can analysis reaction force acting on damper plate.
