注射模设计的三维模型发展

注射模设计的三维模型发展(中文7100字,英文4600字)
如今，为了使注塑工艺变得更简单，很多嵌入式软件都在高级3D 注塑平台的基础上开发出来的，诸如有限元分析，计算机辅助制造，注射模设计，模拟以及形象化设计。这些软件都是很有利的。然而，它关非没有缺点。事实上，这些嵌入式软件也可以通过低级的3D更灵活和更轻便性开发出来。这篇文章查阅了各种各样基于3D应用发展的期刊和方法，主要是关于软件方面。首先，提出了一种基于3D的应用发展的方法，这种观点通过使用Parasolid模型的注射模实现的。基于在已建立的模具设计中的模具设计概念，文中说明了一种被叫做IMOLD的模件。在一个Windows NT 平台上，面向对象的编程语言被用来开发这种软件。

Three-Dimensional Kernel Development for Injection Mould Design

Today, many software “plug-ins” have been developed on high-level 3D modelling platforms to facilitate processes such as FEM analysis, CAM, injection mould design, simulation and visualisation. Such an arrangement is advantageous in many ways. However, it is not without shortcomings. Ideally, these “plug-ins” could also be developed using low-level 3D kernels for higher flexibility and better portability. This paper examines the various issues and methodologies related to the development of such 3D-based applications. The emphasis is placed on the software aspect. First, a methodology for the development of 3D-based applications is proposed. The idea is then implemented by developing an injection mould design application using a low-level 3D kernel called Parasolid. Based on design concepts used in an established mould design appli¬cation, IMOLD, the development of a mould base design module is illustrated. An object-oriented programming langu¬age has been chosen for the development of the software on a Windows NT platform.
