As an effort to solve problems occurring in the current modular machine tool design, KBE technology is introduced into the field. The combination of modular machine tool design and KBE strengthens the inheritance and reuse of design knowledge, achieves an intelligent design for general machine tools and provides a reliable technical support for modular machine tool design. The components of the system...
To organize an ideal dynamic alliance, choosing and optimizing manufacturing resources are very important. In this paper, a manufacturing resource choosing method based on CBR (case-based reasoning) was introduced. A method of calculating the similarity degree between the original cases and the retrieved ones was proposed, which was based on the combination of grey-relation theory and fuzzy-set theory...
To obtain ideal shape of electrodynamic shaker skeleton, a border shape analysis-based electrodynamic shaker skeleton optimization approach was introduced in the paper. The shape of the skeleton of electrodynamic shaker was optimized to meet the requirements of the simulative math model of the first-order inherent frequency. The final analysis result demonstrated this approach was a feasible and efficient...
To manage the knowledge of product development period efficiently, a PDM-based product design knowledge management model was proposed. According to the different characters of tacit knowledge and explicit knowledge, a design knowledge classification and related-representation method were introduced. The integration model between PDM and product design knowledge flow which is the key part of the design...
To meet the needs of knowledge management for product development, a knowledge active push model was proposed. The knowledge flow of the active push mechanism was analyzed as well as design knowledge organization and knowledge match of the system. A multi-table-based knowledge discovery method was introduced. To push the right knowledge to the right person, a knowledge-weight-based active push algorithm...
A vehicle windshield inspection gauge digital design system was developed through the integration between knowledge-engineering-related technology and product parametric design technology, based on Siemens PLM Software NX development platform and with the application of software tools such as UG/Open API, UF, UlStyler, MenuScript. Some key technologies such as Knowledge mining and classification,...
Based on the analysis of traditional high power oscillator, a brand-new oscillator of single-skeleton, dual-coil style is introduced to eliminate the steep troughs and peaks existing in the frequency curve produced by traditional high power oscillator. At the same time, the shape of the skeleton is optimized which minimizes additional mass effect on the evaluated object and broadens the oscillatorpsilas...
The research of this paper was based on V-model dual-moving-coil electrodynamic oscillator. The finite element model of the oscillator mobile system was established in the paper. The subsequent model analysis revealed that the steep troughs and peaks existing in the frequency curve result from the axial symmetric structure of the mobile system. The findings can provide basis for further structural...
To design dirt separator rapidly and accurately, a knowledge-based product automatic design system was introduced in this paper. A way of adopting knowledge reuse to customize dirt separators was employed as the key technique of the system. According to the requirements of the automatic design system, a knowledge classification method was put forward, and the basic knowledge, design process knowledge...
The data security is one of the biggest problems which inhibit the further application of the ASP platform. This paper put forward an ASP-based security system strategy which includes infrastructure security, safeguard security boundary and computing environment protection. An ASP-oriented intrusion detection model was also proposed, and the intrusion detection subsystem function was analyzed in detail...
To integrate manufacturing resources is an important way out for small and medium-sized enterprises (SMEs) to compete with big ones. An e-hub-based manufacturing resources integration method was introduced, which can decrease the running costs and improve competence and resources utilizing efficiency of the enterprises. E-hub-based application integration frame and mode was illustrated in detail....
To choose and manage networked manufacturing resources efficiently, a fuzzy association rules mining technique was proposed. According to the analysis of all data types, a specialized data preprocessing method was applied to extract, wash and transform networked manufacturing resources data, and a self-contained data warehouse on networked manufacturing resources was established for data preprocessing...
