- Abstract
- Lock-up clutch of a torque converter in an automatic transmission directly transmits 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. In addition to that, this part helps the improvement of total vehicle systems by increasing spring characteristic in aspects of the design facilities. To analysis the dynamic hysteresis of damper springs, numerical simulation has been carried out using DAFUL, a dynamic analysis commercial code. Preliminary test has also been conducted to assess the dynamic behavior of damper springs. The results of analysis and test are discussed in view of the dynamic simulation of damper springs.
