Abstract

Abstract: To improve the performance of torque converter, some blade parameters were selected as variables and then optimized by orthogonal DOE (design of experiment) which based on the three dimensional flow simulation. The variables were selected through theory of hydrodynamic torque converter design and the analyzing of flow field in it. Firstly, optimal models respectively taking the stall torque ratio and top efficiency as target function were set up to get two optimal target values. Then, these two values were used to form a new function as target for next optimization. The result indicates that the stall torque ratio and top efficiency increase by 7.3% and 1.5%, respectively after the optimization proves the efficiency of this approach and its value to engineering.

Key words: turn and control of fluid, hydrodynamic torque converter, computational fluid dynamics, blade parameter, optimal design
