Infromation data about oil pump’s rotate speed, supplying pressure, oil temperature and oil flow rate were obtained by CFD simulation analyzing.
ANN model that used to describe the delivery performance of oil pump was employed, and the model was trained by learning samples from those CFD simulation results.
