| Abstract: | Cylinder liner wear is an important factor to measure the life of engine.In view of the defect of traditional grey prediction model(GPM),a mean correction strategy is adopted to conduct the preprocessing of sample data and realize the optimization of GPM.By combining GPM with BP network,the optimized gray neural network prediction model is established.The results of real case analysis show that the optimized model can more accurately predict the wear of cylinder liners,providing a more effective way of engi... |
