자동변속기용 토크 컨버터 성능 최적화에 관한 연구 = A Study on Performance Optimization for Torque Converter

다국어 초록 (Multilingual Abstract)

To improve vehicle performance, development of the torque converter matching to advanced engine performance is essential. The improvement of the torque converter’s performance could be optimized by modifying geometry of 3 elements of the torque converter. The impeller and turbine of automotive torque converters are usually made of stamped sheet metal parts. Any geometry modification of the impeller or turbine would be very expensive because of tooling cost. In contrast, the stator is usually made of aluminum die-casting. Torque converter modifications are limited to the stator only in order to reduce the manufacturing cost. By the Computational Fluid Dynamics, the variation of stator shapes were analyzed and designed. To verify the accuracy of CFD, performance test was done with samples. In comparison of analysis with test result, both shows similar pattern through overall speed ratio.
