基于BP神经网络的汽车发动机凸轮轴数控磨削加工工艺优化

摘要

随着汽车工业的迅速发展，作为汽车发动机的关键零件，凸轮轴的需求量越来越大，对其加工质量和加工效率的要求也越来越高。本文概述了凸轮轴磨削加工的现状，介绍了人工神经网络特别是BP神经网络的相关理论，最后采用BP神经网络算法对凸轮轴磨削加工部分工艺参数进行优化。%Camshaft is a key part of automobile engine. With the rapid development of automobile industry, the demand for camshaft is growing and the requirements for its processing quality and efficiency are increasingly high. In this paper, the current situation of camshaft grinding is summarized. The artificial neural network theory, especially BP neural network, is introduced. Finally, some processing parameters for camshaft grinding are optimized based on BP neural network algorithm.
