摘　　要：基于轨道车辆S型辐板车轮结构的几何形状特点,在AutoCAD平台上利用其二次开发环境Visual LISP,使用AutoLISP和DCL语言设计出2种S型辐板车轮的交互式参数化模型对话框,实现在S型辐板车轮结构几何形状优化设计过程中,改变所需参数即可自动生成S型辐板车轮的二维截面图,避免了因车轮结构几何形状改变导致重复绘制截面二维CAD图的缺点,显著提高了S型辐板车轮的绘图效率,为车轮结构三维建模和结构FE应力分析提供了基础几何模型。Based on the structural geometric characteristics of the S-type web wheel of the rail vehicle, two interactive parameterized model dialogs of the S-type web wheel were designed by using AutoLISP and DCL language on the AutoCAD platform under its secondary development environment. The two-dimensional cross-section of the S-type web wheel could be automatically generated in the process of optimizing the geometry of the S-type web wheel. The work of repeatedly drawing the two-dimensional CAD drawing of the cross-section was avoided when the structure of the wheel was changed which improved the efficiency of drawing the S-type web wheel and provided the basic geometric model for the three-dimensional modeling of the wheel structure and the FE stress analysis of the structure.
