| 摘 要： | 为准确计算液力变矩器轴向力,提出了基于三维流场数值解的变矩器轴向力计算方法。计算中,利用CFD软件对液力变矩器三维流动控制方程进行数值求解,在数值模拟得到的变矩器内流场速度、压力数值解的基础上,进行轴向力计算。将新的轴向力计算方法应用于变矩器实例,将其计算结果分别与传统方法计算结果以及实验结果进行对比后可知,新方法计算误差明显减小。

| Abstract: | A new calculation method was suggested based on the numerical solutions of the 3-dimensional flow field to calculate accurately the axial force in the hydrodynamic torque converter(HTC).The 3-dimensional flow control equations were solved numerically by means of a computational fluid dynamics(CFD) software,and on the basis of the obtained numerical solutions of the flow velocity field and the flow pressure field in the HTC,the axial force can be derived.An application case of the new method was demonstrated... |
