동적 거동을 이용한 토크컨버터 록업 클러치 면압 분포에 관한 연구

The Lock-Up clutch of a torque converter directly transmits the engine power to the automatic transmission in order to achieve a more fuel economy. Friction facing, a core part lock-up clutch system, is generated high heat and facing-pressure because of the relative RPM of friction plate and engine when lock-up clutch is operated. To reduce more fuel consumption, the slip is generated between a friction facing and a front cover for torque converter lock up clutch. This paper discussed facing-pressure distribution of torque converter using the dynamic motion. To analysis the dynamic motion of friction facing, numerical simulation has been carried out using Lock-up Clutch Analysis Toolkit made by OPEN API module in DAFUL. This paper is provided torque converter engineer with useful information for lock-up clutch design.
