摘要: 传统参数化方法难以适应变结构体设计,提出基于AFV(Abstract-Fuse-Verification)
技术的变结构体参数化设计方法。AFV 技术通过Abstract 将零件不同部位抽象形成模板库;Fuse
支持部位模板的设计和任意组合,提高了对变结构体设计的适应能力;Verification 按相关标准
校核结构尺寸以防止非法拓扑变异。而且,AFV 技术内部的类结构支持插件在不同CAD 平台
间切换。基于AFV 技术开发铁道车辆车轴参数化设计插件,实现了车轴的高效快速设计,验证
了AFV 技术的可行性。

Abstract: The traditional parametric method is difficult to adapt to variable structure design,
presented a new parametric method in varied structure designing which named as AFV
(Abstract-Fuse-Verification) technology. First, the component are abstracted into different parts,
forming template library; then each part can be designed separately and any combination of parts is
supported, improving the ability to adapt to the design of variable structures; the dimension of each
part are verified finally in accordance with the relevant standards, avoiding illegal topological
variation. In addition, AFV technology support the plug-in switching CAD platforms. The railway
vehicle axle plug-in based on UG platform being developed using AFV technology, shows the
feasibility of this tech.
