飞机结构试验加载杠杆系统设计是一项繁复的工作，而利用 CAD 软件的

参数化功能可以轻松实现杠杆的设计与虚拟装配。本文介绍了基于 Automation

技术的加载杠杆系统参数化建模方法，使用 Visual Basic 开发了相应可视化建模

软件。应用实例表明，软件界面友好，操作简单，只需输入试验加载点、杠杆布

置等基本参数和数据文件，即可完成杠杆系统的参数化建模，从而快速地实现加

载杠杆系统的参数化设计与方案展示。-Aircraft structural test load lever system design is a complicated task, parametric CAD software can easily leverage design and virtual assembly. This article describes the loading lever system parametric modeling method based on Automation Technology, developed using Visual Basic the corresponding visual modeling software. Application examples show that the software interface is friendly, easy to operate, simply enter the basic parameters of the test load point, lever arranged and data files, to complete a system of levers parametric modeling, parametric design of the loading lever system to quickly achieve Plans show.
