摘要

Based on a type of stamping welding hydraulic torque converter, a blade thickness full factor test was designed. Firstly, the main effects and the interaction effects of torque converter external characteristics were analyzed, combining with numerical simulation of flow field. The results show that, the main effects make the capableness of the torque converter descend along with the blade thickness increasing and the interaction effects of blade thickness are not obvious. And then, the numerical variation effects of blade thickness on performance were analyzed. The results show that, the increased thickness of the vane can induce a decline of the torque transmitted by the torque converter and this decline is from slow to fast. Finally, the blade thickness was optimized based on the study results. Combined with the actual thickness of the engineering board, the blade thickness was determined and a verification test was carried out. Similar to the variation of pump rotation moment with blade thickness, turbine torque decreases with the increase of blade thickness, especially in the low speed ratio region of torque converter. When the blade thickness is within 3 mm, for each increase of 0.5 mm thickness, the turbine torque value decreases by 0.5%, and when the blade thickness exceeds 3 mm, the turbine torque changes faster, and for each additional 0.5 mm, the maximum change of the pump rotation moment is about 3.8%.
