The development period of the torque converter, which is one of the key components of the car power train, was shortened due to the shortening of the development period of the new car. Also price competitiveness has become an indispensable factor in new car development. Under these circumstances, parametric design modification of a torque converter stator is an effective way to adjust the torque converter performance. However, it is difficult to quickly confirm the results of the parameter design modification because CFD analysis takes considerable time to analyze torque converter performance depending on speed ratio. Therefore, in this paper, we aim to identify the parameters that have the greatest influence on the performance and identify the direction of the product design in a short time by grasping the tendency of a few CFD analysis results. In this case, multiple linear regression analysis was used to derive the predictive equation with high correlation coefficient and adjusted coefficient of determination. The average error between the predicted value and the CFD analysis result is within 1.0% and reliable results are obtained.
