| The approximation to the longitudinal-section contour of piston skirt based on BP neural network |
|
|
| Abstract: |
| Based on the concerned methods for approximating the longitudinal-section contour of piston skirt,one new approximating method based on BP neural network is presented in this paper.The results of different approximating methods are compared.The results illustrate that the new method can be used in different types of piston skirt,and it can get better result. |
| Key words: BP neural network piston skirt longitudinal-section contour |
