基于AFV 技术的变结构体参数化设计方法研究

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。

Research on Variable Structure Parametric Design MethodBased on AFV Technology

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.
