【摘要】：在全球经济一体化的今天，，金融危机是人类都不愿发生的事情，就最近的“美国次贷危机”都还让人们心有余悸。然而在这次金融危机中受影响最小的就是制造业，曾经被人们一度认为是“夕阳产业”,经过这次金融危机的洗礼后让人们重新审视这个坚挺的老牌行业。在这次金融危机后人们开始认识到要大力发展制造业。而当今的制造产业尤其是机械制造业，一方面要满足市场需求，另一方面要保证产品质量，提升市场竞争力，这就需要以先进的技术手段为支持。所以在机械产品开发，设计，制造，装配等各个环节都应用了各种各样的CAD软件。这些CAD软件不仅保证了产品的质量还能满足现代日新月异的开发需求。产品的造型和装配等各个机械生产环节都通过运用这些软件来提高自己产品的竞争力。本文就研究了UG软件在齿轮泵的参数化建模和Virtools软件在齿轮泵装配中的应用。论文以圆柱直齿轮泵的模型为例，深入研究了该模型的参数化设计及虚拟装配问题。以强大的三维设计软件UG（Unigraphics NX）作为其开发平台，运用该软件的二次开发工具UG/Open Grip及Visual C++编程软件，实现齿轮泵的直齿轮轴的参数化造型并完成直齿轮轴的参数化设计系统。在完成直齿轮轴的三维模型后，可以创建其它零部件三维模型，并完成齿轮泵的虚拟装配。然后，把在UG中建立的齿轮泵的三维模型导入到3Ds Max进行优化渲染，最后利用Virtools平台开发了齿轮泵虚拟装配系统。在UG软件中实现了对直齿轮轴的参数化设计，这样可以快速、准确的生成所需要的三维模型，并完成了齿轮泵的所有零件的建模及其装配。在Virtools软件中，以直齿轮泵为研究对象，深入探讨了以直齿轮泵虚拟装配过程。同时利用视图的切换功能，使其装配过程真实、明了，还可以达到装配教学的目的。
[Abstract]:In today's global economic integration, the financial crisis is something that human beings do not want to happen. The recent "subprime crisis" in the United States is still a source of dread. But the least affected of the financial crisis was manufacturing, once known as the "sunset industry." After the baptism of the financial crisis, people have re-examined this strong old industry. After the financial crisis, people began to realize the need to vigorously develop manufacturing industries. Today's manufacturing industry, especially the machinery manufacturing industry, on the one hand to meet the market demand, on the other hand, to ensure the quality of products to enhance the competitiveness of the market. This needs to be supported by advanced technology. So in mechanical product development, design, manufacturing. Various CAD software are used in assembly and other links. These CAD software not only guarantee the quality of products but also meet the requirements of modern development. Product modeling and assembly and other mechanical production. This paper studies the parametric modeling of gear pump and the application of Virtools software in gear pump assembly. This paper takes the model of cylindrical straight gear pump as an example. The parameterized design and virtual assembly of the model are deeply studied, and the powerful 3D design software UG(Unigraphics NX is used as the development platform. UG/Open Grip and Visual C programming software are used to develop the software. The parametric modeling of spur gear shaft of gear pump is realized and the parameterized design system of straight gear shaft is completed. After completing the three-dimensional model of straight gear shaft, the three-dimensional model of other parts can be created. The virtual assembly of gear pump is completed. Then, the 3D model of gear pump is imported into 3Ds Max to optimize rendering. Finally, the virtual assembly system of gear pump is developed by using Virtools platform. The parametric design of spur gear shaft is realized in UG software, so that the needed 3D model can be generated quickly and accurately. The modeling and assembly of all parts of gear pump are completed. In Virtools software, the straight gear pump is taken as the research object. The virtual assembly process of a straight gear pump is discussed in depth. At the same time, the function of view switching is used to make the assembly process real and clear, and the purpose of assembly teaching can be achieved.
