CFD Calculation Method Improvement for Torque Converter after Coupling Point

摘要:

着眼于液力变矩器在耦合工况之后乃至倒拖工况的仿真计算分析方法研究，以改变在液力变矩器传统的仿真计算中耦合点之后的液力性能计算并不能被很好呈现的缺点，通过CFD(computational fluid dynamics)及最小二乘拟合的方式加入了导轮在耦合工况内的影响，对液力变矩器企业开发过程有着现实意义.

Abstract:

This study, which uses CFD(computational fluid dynamics) and linear extrapolate and adds stator speed effect at coupling condition,can solve the problem that in the current CFD calculation way, the hydraulic performance of torque converter above the coupling point can not be accurately simulated. The method can reach the good result and provides the good contribution to the design of the torque converter in the companies.
