导轮结构形式对液力变矩器性能的影响

utomotive torque converters have been designed with a smaller axial size bacause of the space restriction.The width of the stator has a significant effect to shorten the axial lengeh of a torque converter.Two torque converters are designed to investigate the effects of the width of stator. Computational analysis with three dimendional CFD software shows the internal flow field of the torque converter,also the performance. The effectes of the width of the stator to inner flow field are got by analyzing the CFD results. By comparing with the performance of torque converters,the influence rules of the width of the stator are found out.
