基于AFV技术的变结构体参数化设计方法研究

Research on Variable Structure Parametric Design Method Based on AFV Technology

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。

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.
