摘要：
In order to rapidly solve the dynamic response of circulating flow rate of torque converter, a transfer functions representation method for dynamic circulating flow rate is proposed. In this method, through the derivation on the basis of one-dimension flow theory, a torque converter with certain structure is selected as the research object, and dynamic circulating flow rate is regarded as a first-order linear system's response with the input of static circulating flow rate. Then, the transfer function of dynamic circulating flow system is constructed according to the static and dynamic CFD (Computational Fluid Dynamics) simulation data under simple working conditions in torque converter's common working range. Simulated results show that the proposed method helps achieve a fit goodness of 0.987 for dynamic circulating flow rate prediction in common working range, and a fit goodness of 0.95 for input and output shafts' dynamic torque prediction; and that, in comparison with CFD simulation, the proposed method greatly increases the calculation speed only with a slight decrease in calculation accuracy, so that it is effective in rapidly solving the dynamic response of torque converter. © 2016, Editorial Department, Journal of South China University of Technology.
