A Guiding Design System for Pressure Vessels based on 3D CAD

The design of pressure vessel is an extremely professional job which has heavy workload, repeated work, and rich accumulated knowledge, and it has good characteristics of serialization, generalization, standardization. Generic 3D CAD systems are not suitable for pressure vessel design. On the contrary, customized development based on 3D CAD system is needed. In this paper, a new pressure vessel design system based on Chinese 3D CAD system named SINOVATION was developed to improve design efficiency and accuracy. First, the functions and construction of pressure vessel design system were presented with the analysis of the traditional design process of pressure vessels. Second, related design specifications were managed and used flexibly in pressure vessel design system, and general parts library and standard parts library were established to improve parts reuse and accumulation. Finally, a guiding design mode was accepted for typical vessels and components to design same product series while direct modeling function was used for atypical pressure vessels. The results show that this method is helpful for embedded use of design specifications, standards and knowledge, and also provides an extensive interface for product updates and diversification. Statistical data reports and accurate engineering drawings are generated automatically based on 3D models. The quality, efficiency, and consistence are greatly improved. With the implementation and application, the system has been highly commended by customers in Chinese pressure vessel industry, especially in petrochemical industry.

NX Reuse Library Workflow Based on Knowledge

In reuse library platform, realizing the reuse process of standard parts and common parts and building standard part management system are the important application during the whole design field. This paper introduces the method of customization standard parts library using part family, and realizes standardization management of reuse library. By creating KRX files, the knowledge components in reuse library are managed. Reuse library is an effective way to organize and use standard parts and common parts.

Non-Standard Parts Model Library Based on VIRTOOLS

With the new equipment research preparation put into use, in order to ensure special purpose forces, in the existence of a large number of new equipment nonstandard parts. These non-standard parts in the various aspects of the new equipment play a great role. This topic-based VIRTOOLS 5.0 software to establish a non-standard parts library in new equipment, new equipment, used to strengthen the management and maintenance of non-standard parts for the maintenance of armed forces provide a solid guarantee. Meanwhile, from the user maintenance reality, virtual assembly of non-standard parts, non-standard parts for the maintenance provide effective protection.

The Parameterization Design of Standard Parts Based on UG Part Families and Excel Database

With the development of mechanical industry, more and more standard parts have been used in all kinds of large assembly process. The same kinds but different types of standard parts are used, making it boring and difficult to build standard parts. Therefore, this article describes a rapid modeling method of standard parts Based on UG Part Families and Excel database. According to the concrete examples, the procedures for establishing the standard parts library were presented. The method is simple and practical, no secondary development is needed and the design efficiency is increased.

Study on Mould Design with NX Based on Knowledge Reuse Technology

Mould design is a complex process which mainly uses fixed design process or design approach. It has certain similarity or repeatability. In order to avoid duplication of effort and improve the efficiency of the mould design, present a mould design method based on NX knowledge reuse technology, establish the standard parts library, so as to realize the target of high-quality, short-cycle and low-cost in mould design. At last, the mobile phone shell mould design example is given to verify the feasibility and practicability of the mould design based on NX knowledge reuse technology.

PC the Study of KF Technology in Metal Mold Standard Components Modeling Application

Discusses the Dongguan Changan mold in economic development status and the necessity to establish mold standard parts library, study the technology and related steps for product design in UG / KF environment. Using this technology to solve the problem, unable to integrate into traditional CAD design engineering knowledge and laid the foundation for enterprise storage and reuse of design knowledge, to improve design efficiency and quality and to further the design of intelligent rapid response.

The Research and Development of VB and Solidworks-Based 3D Fixture Component Library

The rise of the Flexible Manufacturing System (FMS) and the Computer Integrated Manufacturing System (CIMS) put forward a more urgent need for the practical fixture design software. 3D Visual Basic-based standard parts library is proposed in this paper. By calling the Application Program Interface (API) functions of Solidworks as the secondary development, the 3D standard parts library is established. And then the application program is made as plug-in to hanging onto the menu of Solidworks operating environment. When the assembly design starts, users can select the standard parts they need by clicking Solidworks menu. And then the application program can automatically query all the data required for drawing pictures. Finally the 3D entities of standard parts are generated so that they can be adopted for the assembly environment.

Modeling Method of 3D Standard Parts Library Based on Virtual Prototyping Technology

This paper proposed a virtual prototyping-based modeling method of standard parts library. After the design requirement analysis, the modeling approach was put forward. Then the parameter-driven method and its use method were then proposed. The classes object organization relationship was identified step by step. The fastening feature tree structure logical relationship was present as an example, which demonstrates that this method is obviously helpful to product design.

Research and Realization of Hex Nut Standard Parts Library Based on Reusable Knowledge

Product design requires a large amount of standard parts, But standard parts sort is various, In order to avoid duplication of work and Improve the efficiency of design, The establishment of standard parts library is very necessary, it Can reduce the repeated work and the cost.
