阿基米德圆柱蜗杆参数化设计

Parametric Design of Archimedes Cylindrical Worm

摘要: 为提高阿基米德圆柱蜗杆的设计效率，减少人工计算和建模过程中的重复性工作。本研究基于VBA (Visual Basic for Applications)语言，结合SolidWorks二次开发接口，先后进行了宏录制、原始代码修改调试、改写几何坐标、编辑交互窗口、编写强度校核公式等操作，编写了一套阿基米德圆柱蜗杆的自动参数化设计程序。该程序能够根据用户输入的参数，如蜗杆的模数、蜗杆分度圆直径、蜗杆头数、涡轮齿数以及蜗杆旋向等，自动生成精确的阿基米德圆柱蜗杆三维模型，并输出强度校核报告。并且该程序具有较高的实用价值，可广泛应用于机械设计领域，尤其适用于需要频繁调整蜗杆参数的优化设计场景。未来可进一步扩展程序功能，如支持更多蜗杆类型或集成有限元分析模块，以提升其工程适用性。

Abstract: To improve the design efficiency of Archimedes cylindrical worms and reduce repetitive manual calculations and modeling processes, this study developed an automated parametric design program for Archimedes cylindrical worms using VBA (Visual Basic for Applications) language and SolidWorks’ secondary development interface. The development process involved macro recording, modification, and debugging of original code, rewriting geometric coordinates, designing interactive windows, and formulating strength verification equations. The program allows users to input key parameters such as the worm’s module, pitch diameter, number of threads, number of gear teeth, and worm direction to automatically generate precise 3D models of Archimedes cylindrical worms and output strength verification reports. This program demonstrates high practical value and can be widely applied in mechanical design, particularly in optimization scenarios requiring frequent adjustments to worm parameters. Future enhancements may include support for additional worm types or integration of finite element analysis modules to further improve its engineering applicability.
