机械装置基本设计的创造方式可以分为两种类型：创造出从未有过的一些或全部可能的设计概念；创造出与现有设计具有相同拓扑特性的更多的或全部可能的设计概念．该论文首先介绍了一种现有的机械装置的创造性设计方法．这种方法系统地计算了全部可能的拓扑构造，这些构造与设计的要求和约束是相一致的，并与现有的设计具有相同或相似的功能，从而得到新的产品设计，避开已有的产品设计专利．从这一创造性设计方法出发，该文提出了一种实现该方法的辅助设计系统模型，着重分析了系统的框架结构和功能、人机交互等关键技术．通过该系统模型的提出，较好地实现了创造性设计方法的辅助设计系统，从而为机械设计人员积极从事创新设计、缩短机械装置设计周期起到了一定的促进作用．该课题来源于浙江省制造业信息化工程重大科技攻关项目——“基于支持智能化缝纫机创新的开发平台99通过对创造性设计方法的应用研究，使得这一辅助系统在项目的投资方(浙江飞跃缝纫机集团)的研发部门得到普遍应用，对于加速该部门新零件、新产品的开发，起到了一定的推动作用． 相似文献

Representations of contemporary rapid prototyping (RP) technologies may not be able to manage and share data processing information based on network. This paper presents a new approach, together with its technical implementation, to solve this problem, and discusses web-based study on RP data processing techniques. At present STL files produced by 3D modeling systems contain triangular facet representation of surfaces and have become standard data inputs of RP and manufacturing systems. The paper proposes algorithms for correcting common errors, and optimizes the algorithm of gaps or hole errors leading to open loops in the data structure based on analyses of the rules and errors in the STL file. In addition, effectiveness of the approach is demonstrated by a simple model view example of STL files based on Java 3D technology. 相似文献

Product data management (PDM) is a unique technique that integrates and manages all applications, information and processes defining a product from design to manufacture, and to end-user support. However, exploration of valuable information and knowledge from the PDM system has become a key in improvement of efficiency and implementation of knowledge management in an enterprise. This paper introduces a data mining prototype system model based on PDM, and emphasizes some important techniques such as design of the prototype system framework, methods of data selection and integration of data mining prototype system and PDM. The model basically solves the problem of functional losses in mining and analyzing data in PDM. Application of data mining to PDM is meaningful to the ideas and techniques of PDM, and to the rapid development of data mining application itself. Also, it is useful in improving development and usage of enterprise databases. 相似文献
