摘要
本文建立了以最小时差理论为核心的驼峰溜放纵断面的优化模型,并采用约束变尺度法进行计算,应用GKS 图形标准开发后置图形处理模块,实践表明,该 CAD 系统对驼峰溜放纵断面设计具有一定意义.
Based on the theory of minimum distance of time,a new optimal model of humping profile is set up and calculated with the constrained variable metric method.Using GKS graphical standard.develops a graphical module for post-processing.The practice shows that the CAD system used for the design of humping profile has great significance.
