摘要：

为提升液力变矩器性能的同时优化内部流场载荷分布,在对变矩器叶片设计过程中通过对泵轮动力载荷的合理设计,采用反设计方法并基于流场特性对变矩器能容性能进行定向设计,通过优化叶片形状增大液力元件的能容,同时改善流场平顺性。设计结果表明,反设计方法使泵轮能容提升了5.2%,同时内流场施加到叶表的载荷幅值下降了4.9%,反设计方法实现了泵轮能容的定向优化设计。

Abstract:

To optimize the blade shape while improving the flow field distribution characteristics, an optimization design of the impeller’s capacity performance is proposed by designing the blade load distribution of the impeller and combining the inverse design method in the capacity design process of the torque converter. The results show that the proposed design method can increase the impeller’s capacity coefficient by 5.2%, while the load amplitude applied to the blade by the internal flow field is reduced by 4.9%, indicating that the inverse design method can realize the optimization of capacity.

Key words: inverse design method, hydrodynamic torque converter, cascade system, blade load distribution, directional design
