Abstract

The double arc oil grooves friction pairs in HVD was analyzed in order to reduce the drag torque of hydro-viscous drive (HVD) and decrease the no-load power loss of friction pairs. The iSIGHT integrated optimization design platform of friction pairs in HVD was built based on the computational fluid dynamics flow numerical simulation, the design of experiment (DOE), the response surface methodology (RSM) and the numerical optimization algorithm. The influencing and sensitivity analysis of frictional pairs oil grooves parameters on drag torque was analyzed. The grooves structure parameters were optimized. Results indicate that the drag torque is monotonously decreased with the increasing of the width and depth of oil grooves, and the drag torque is monotonously increased with the increasing of the number of oil grooves. The optimized friction pairs can reduce the drag torque of HVD by increasing the width and depth of oil grooves and reducing the numbers of oil grooves, thus improve the power output of engine.
