Abstract

One-dimensional flow bundle theory is unable to quantitatively predict the influence of blade number on hydraulic torque converter performance. And there exist various combinations and huge calculations in blade number design based on 3D fluid analysis. Thus a blade number neural networks model of hydraulic torque converter was constructed. The accuracy of 3D fluid analysis results was confirmed in comparison with the bench test data

and simulations were arranged reasonably by orthogonal experiment method. 3D fluid simulation results were regarded as the training samples of back propagation(BP)neural networks. To improve design efficiency and convergence accuracy

genetic algorithm was introduced for optimizing initial weights and thresholds of BP neural networks

which achieved accurate predictions for non-training sample sets. The experiments show that blade number neural networks model serves as a bridge for hydraulic torque converter customization design based on vehicle performance matching.
