膨化机三维参数化设计系统的研究

详细介绍了基于机械自动化设计软件Solidworks研制的膨化机三维参数化设计系统的功能结构、人机界面和关键技术的处理方法。该系统完全被封装在Solidworks的一个菜单项下,通过简单的人机交互,输入功率、转速等设计参数后,它就能自动完成整台膨化机的结构设计,包括膨化腔、带轮传动和减速箱传动的全部设计过程,具有一定的智能化,然后根据用户选择输出零件或者装配体的三维实体模型和工程图。零件自动三维造型的实现采用了以尺寸驱动为主,程序驱动为辅的编程思想,并建立相应的膨化机模板零件库。整个系统程序使用VisualC 语言开发,以动态链接库的形式嵌入Solidworks系统,实现了与Solidworks软件的无缝结合。配合Solidworks强大的三维造型、设计和装配功能,极大地提高了膨化机设计的效率、精度和质量。

The study on system of 3D parametric design of extruder

The paper illustrates the function, UI(User Interface), structure and key technology of the Extruder CAD system, which is based on Solidworks. The whole system is encapsulated in a menu of Solidworks. And after some parameters, such as power and rotational speed are imported through UI(User Interface), the system will automatically complete the design of extruder, including the whole process of design of the extruder case, system of pulley transmission and reducer transmission. Then 3D models and engineering drawings of parts or assembly can be exported according to the choice of user. The realization of the automatically 3D modeling adopted the idea of being driven by dimension primarily and being driven by program secondarily. Visual C develops the program of the system, and it can be compatibly added to Solidworks as dll (dynamic linkage library). Combined with functions of 3D modelling, design and assembly of Solidworks, the efficiency, precision and quality of design of extruder are greatly improved.
