Abstract: Integral production technology of impulse turbine runner effectively prevents phenomenon of bailer broken when generation unit working, and then improving its service life. Based on comprehensive application of vibration inhibition technology and machining optimization path CAD/CAM technology, the high-speed plunge milling process is forwarded in this paper under the condition of big slenderness ratio and be able to present processing vibration. By using matching principle of tool connection point surface smoothing processes and the helix curved surface processing method this process successfully solves the problem of interfering point state complex in finishing plunge milling impulse water turbine whole runner and it achieves high active finish machining by three-axis NC process. This technology has also successfully been used in the power station whole runner manufacturing process in HPE group.

Abstract: The thesis researched the relationship between green design and reconfigurable on NC machine tool, and expatiated that the development of the reconfigurable machine tools is essential. This article has carried on the analysis from the deep hole components classification and the formed movement craft two aspects to the deep hole components race. The reconfigurable deep hole machine tool was to carry on the modular design based two aspects for the module partition and reconstructable analyze, solved the key technologies the machine tool modulation design. From the machine tool bed module, the head of machine tool module, the cutting tool auxiliary system and the numerical control system four aspects, to design and research on reconfigurable machine tool, solved the difficult design problem which the part reconfigurable designed.

Abstract: Focused on medium and small sized logistics enterprise (MSLE) in China, the characteristics are analyzed and existing issues are addressed based on the comprehensive investigation results of current levels of informatization of MSLEs covering investment, infrastructure, awareness, strategy, integration, standardization and qualified talent. Taking full consideration of China’s national situation, the development opportunities of MSLE’s informatization are discussed in terms of the powerful national informatization strategy, the key support on logistics industry, the pressing demand on logistic service generated by manufacturing industry, the intense competition among logistics software suppliers, the rapid development of public logistics information platform and advanced logistics technology development. Furthermore, the corresponding countermeasures at the aspects of enhancing soft power, utilizing external consulting services, popularizing compact and efficient information platform, keeping fast and smooth informatization construction policy, and strengthening project management and associated regulations are presented to help promote the informatization progress of MSLE in China.

Abstract: Verisimilitude of 3D face modeling can be strongly enhanced by taking into account skin wrinkles. However, there are two difficulties to model real and natural wrinkles: one is the location of wrinkles and the other is the shape of wrinkles. For the first problem, an algorithm for locating wrinkles through extracting feature curves based on photo is presented; For the second problem, a shape control function is proposed considering the properties of real wrinkles, which could provides intuitive parameters for easily modulating the depth and the width of wrinkles, and express the attenuation and impact of one wrinkle on its surrounding surface. The experiment results by applying the method to a 3D face model show that it not only has the advantage of verisimilitude as the photo, but also has the feature of natural ripple which is deeper and wider in the middle than in both sides.

Abstract: Patterns have become a more effective way on the knowledge use of the HCI domain. These patterns are mainly oriented to different tasks, which are too coarse-grained to be easily implemented. And it is not given that how to use these patterns to built user interfaces in engineering way. Furthermore, many different patterns are oriented to different models in the model based on user interface (UI) development, which are hard to be integrated into the UI development tool. In point of increasing UI knowledge reuse, every UI is divided into many presentation units (PU), which reduces the grain of UI. Next, the UI feature space is given through three facets and various relations among these facets. Therefore, the Engineering-oriented User Interface Design Pattern (EUIDP) is proposed from the interior model, the presentation model and the operation model. As a case, the Grid EUIDP is explicitly described according to the form of EUIDP. Finally, the conclusion and the further work are discussed.

Abstract: Although QFD is powerful for translating customer requirements to control parameters of product design and production process, how to capture and understand requirements rapidly, accurately and economically so that the products can deliver themselves of customers is still a bottle-neck. This paper proposes a theory framework for capturing customer requirements. First, the problem for customer requirements capture is formalized. Second, three phases including requirements gathering, requirements mapping and requirements evaluating are advanced, and a method named iterative arithmetic to determine the weights of requirements is also developed. Finally, the proposed methodology is effectively demonstrated in an instance of requirements capture for reading lamp of computer.

Abstract: Customized product development is facing the challenges of maintaining mass producibility and exploring customer perception on target products. The objective of this study was the application of ergonomic evaluation method for customized furniture design in virtual environment. At the first, the system architecture was built, and gordian techniques of the system were analyzed. Then a representative case was studied. In this case study, 3D scanning system and Motion Capture were used to get information of given user/users, REBA and Lifting Index (LI) of revised NIOSH lifting equation were selected as ergonomics evaluation methods. The prototype’s usability was verified by the result. This method can also be used to solve other relative problems.

Abstract: A kind of ridge-till and no-till wheat seeder was developed according to the agricultural requirement of mulching with high maize stubbles. The three-dimensional models of the seeder were built with the software of Autodesk Inventor, including the frame, openers, reshaping devices, combined press roller and driving wheel devices. Reshaping devices were designed to reshape the former ridges, while combined press roller is used to press ridge sides and seeding zones simultaneously. Based on the parts modeling, the virtual assembly model of the ridge-till and no-till seeder was constructed, which can contribute to designing the simulation model of the seeder for dynamics analysis.

Abstract: With accumulating data in mine production, integration of the existing separate information systems is of great importance in enhancement of both production management and support decision-making. BIStar, a production & management decision support system base on data warehouse technology was developed as a user-friendly data analysis, display and decision support tool, and was presented with illumination of its main framework and detailed discussion of its certain key points of the subsystem, such as data acquisition system, central database system, access tools. An application example of information analysis conducted by a large mine corporation was also cited for analysis of feasibility & cost-effectiveness.

Abstract: Due to the uncertainness and fuzziness of image evaluation on product form, many fuzzy multi-criteria decision making approaches are applied in this fields. Fuzzy linguistic is usually used by expert to evaluate the importance of the criteria and to rate the alternatives; hence, we integrating fuzzy linguistic based analytic hierarchy process methodology to image evaluation of product form. Trapezoidal fuzzy number and 11-scale linguistic variables were applied in this model. The proposed approach started by a web-based image evaluation system, and then target products were extracted and divided in many design characteristics. Fuzzy linguistic based AHP was applied to generate the critical forms that ordered by vary image adjectives. A case study of mobile phone design was demonstrated the effectiveness.
