The selflearning train method of the neural network model in wear selfconpensation system

The BP neural network used the tribology system of 45 steel/brass pair s was established and trained by three rules .The network trained by LM ru le l essens quicker and the error was less. The Neural network function in the Matlab toolbox , which could reduce the quantity of the compilation and was applied ea sy by engineers ,was used in the establishment of the network.
