基于BP网络的活塞裙部纵向型线的拟合

The approximation to the longitudinal-section contour of piston skirt based on BP neural network

在分析有关活塞裙部纵向型线拟合方法的基础上 ,提出了基于 BP网络拟合的方法 ;应用实例拟合结果表明 :基于 BP网络的拟合方法适用性广 ,且拟合精度较高。

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.
