| Abstract: | Tank engines of a certain type with different motor hours are tested and by using a pressure sensor,the air compression pressure in engine cylinder is measured.The changing trend of the air compression pressure along the service time of engine is analyzed.The characteristics of cylinder wear and the factors that affect cylinder wear and its lifetime is analyzed.An artificial neural network model for prediction is set up according to the nonlinearity of cylinder wear,and so the prediction of the lifetimes of... |
