叶栅设计是液力变矩器设计的核心,它直接影响到变矩器的性能。在向心涡轮液力变矩器中,以涡轮叶片的转角(β_(T2)-β_(T1))为最大,且流道具有先扩散后收缩的特点。这种相对速度的变化(特别是在扩散区段),就伴随着能量的损失。要想减少损失,就必须保证流通的过流断面积平缓地变化,形成平滑的流道。传统的保角变换绘型法是以手工作图为基础,在很大程度上依赖于人的经验,并且在绘型过程中,要反复检查过流断面积沿流线的
Cascades are the heart of torque converter design and have a direct impact on torque converter performance. In the centripetal turbine torque converter, the angle of the turbine blade (β_ (T2) -β_ (T1)) is the maximum, and the flow channel has the characteristics of first diffusing and then shrinking. This relative change in velocity, especially in the diffusion zone, is accompanied by a loss of energy. In order to reduce losses, it must ensure that the flow of over-flow area changes smoothly, forming a smooth flow path. The traditional method of conformal mapping is based on handwork drawing, largely depends on human experience, and in the drawing process, we should repeatedly check the flow area along the flow line
