The lock-up clutch in the torque converter can improve highly the efficiency of power transfer from an engine by locking up with the transmission gears directly at a high speed instead of fluid coupling. Upon locking up, NVH problems take place due to shudder, friction material characteristics, and so on. Front cover taper angle, friction material, contact surface roughness and damper characteristics are important design parameters for improvement of drivability. Front cover taper angle is based on the surface pressure between front cover and friction facing. In this study, the pressure distribution of the contact surface is analyzed by finite element method. Also, we propose design optimization method for torque converter taper angle.
