基于特征和网络的轨道设计系统的研究

探讨轨道设计系统基于特征的理论模型及其建立方法,建立铁路轨道设计中各类部件（包括钢轨、扣件、轨枕、道床以及道岔等）的理论模型,结合面向对象（OOP）的编程思想对所建立的模型进行分析,通过建立特征类及其继承类的方法描述和实现特征模型;还探讨在AutoCAD设计平台上利用其提供的ObjectARX.NET接口或者dotNET托管程序接口进行二次开发来实现上述人机交互设计系统的思路,同时探讨网络的实时性、安全性和共享性在铁路轨道设计系统中的应用思路。

Study on Railway Track Design System based on feature and network

It was discussed the theoretic model with its establishment methods for the Design System of the railway track based on feature, and instituted the theoretic model of components in railway track design including rail, fastening, sleeper, track bed, switch, etc. It was analyzed the established model with the ideas of Object-Oriented Programming, described and implemented the feature-based model by the methods of establishing feature classes together with their inheritance class. It was also talked about the ideas of how to implement the Design System by the development on the platform of AutoCAD using the interface of ObjecIARX.NET or .Net managed procedure. Finally, it was talked about the application of real-time nature, security and sharing of the network in the Design System of rail track.
