摘　　要：根据误差反向传播(BP)神经网络的原理,结合ObjectARX参数化三维建模技术,开发了基于AutoCAD软件环境的铸铁凸轮轴阶梯式浇注系统智能化CAD软件。文中讨论了系统的构建思想,研究了系统智能化与参数化设计的技术实现手段。结合六缸发动机铸铁凸轮轴HD6105Q 13001的浇注系统工艺实例,给出了智能参数化CAD系统的设计结果。In this paper, according to principles of error back-propagation (BP) neural network, combined with three dimensional parametric modeling based on Object ARX technology, an intelligent CAD software system for step gating system of cast-ironed camshaft was developed, based on AutoCAD environment. Intelligent and parametric ideas of system development and their realizing ways were studied. As an example, a design scheme for gating system of six-cylindrical engine camshaft was provided.
