Abstract

Abstract

In order to shorten the design cycle of torque converter and reduce the dependence of experience in design, the reverse technology was used to calculate and analyze the data of turbine's stamping blades.Based on the generalized torus coordinate system of liquid flow, the mathematical expression of blade design baseline was deduced, the machine coordinates of blade were obtained accurately on both inside and outside rings, and the original characteristic expression of new torque converter was described.Then, new torque converter with designed blades was tested and compared with prototype.Test result indicates that new converter efficiency and torque ratio with new turbine blades are only 0.5% lower than prototype, and the torque coefficient is only 1% lower.The error between new blade and origin one is less than 0.605 2%.Therefore, the torus and axial surface equations obtained from torus coordinate system is accurate.This method offers a new choice to ensure the reliability of product and shorten its cycle in the design of torque converter.
