Temperature Field in Torque Converter Clutch

Torque Converter Clutch (TCC) works longer than ever before because of slipping technology intervention. The friction coefficient of TCC friction plate will change with temperature. In order to get the dynamic friction coefficient and also ensure the friction plate temperature not too high, TCC temperature was calculated on simulation model. First, the work of friction plate slipping was calculated when TCC working; Second, the three-dimensional fluid structure interaction model of Torque Converter (TC) was built basing on CFX, then the temperature field of TC and the Variation of TCC friction plate were simulated; Last, the friction coefficient of TCC friction plate was corrected with its temperature change in real time, and also a temperature threshold was set in order to protect TCC.
