A cylindrical negative Poisson's ratio(CNPR) structure based on two-dimensional double-arrow negative Poisson's ratio(NPR)structure was introduced in this paper. The CNPR structure has excellent stiffness, damping and energy absorption performances,and can be applied as spring, damper and energy absorbing components. In this study, the CNPR structure was used as a jounce bumper in vehicle suspension, and the load-displacement curve of NPR jounce bumper was discussed. Moreover, the influences of structural parameters and materials on the load-displacement curve of NPR jounce bumper were specifically researched. It came to the conclusion that only the numbers of cells and layers impact the hardening displacement of NPR jounce bumper. And all parameters significantly affect the structure stiffness at different displacement periods. On the other hand, the load-displacement curve of NPR jounce bumper should be in an ideal region which is difficult to be achieved applying mathematical optimization method. Therefore, a parametric design strategy of NPR jounce bumper was proposed according to the parametric analysis results. The design strategy had two main steps: design of hardening displacement and design of stiffness. The analysis results proved that the proposed method is reliable and is also meaningful for relevant structure design problem.

parametric design of typical parts holds a very important position during process of product designs. In order to develop a parametric design system of typical parts compatible with heterogeneous CAD systems, this paper presents a framework of a network-oriented design system of typical parts, enabled by eXtensible Markup Language (XML), capable of providing parametric design. Firstly, an overview of the framework is presented. In order to map the part feature hierarchy tree of 3D model into an XML tree, an XML-based part template is introduced. The methods of XML-based parametric design and parametric design navigation are described. Finally, an application example of prototype system under the Pro/Engineer platform is given. The application indicates that the proposed framework is valid for parametric design of typical parts/components in heterogeneous CAD systems.

The creation of hollow out art includes a variety of materials, techniques and categories, its content mostly emphasizes the ancient philosophy performance of the alternation of virtual and real, and Yin-Yang depends on the essence of Chinese culture deduction. If this feature is applied to product design, in addition to emphasizing functional orientation, this traditional arts integration with the new media, will give users a different visual inspire. This thesis is mainly in view of the importance of hollow out art in Chinese cultural heritage, and the 3D hollow out production craft has gradually lost. Therefore, the Delaunay triangle is constructed based on the Convex Hull interpolation algorithm, and the Voronoi Diagram feature is constructed based on the Divide and Conquer algorithm. And with Rhino modeling software as the main body, combined with the application of the parametric plug-in design program (GH), the 3D models of the parametric creative hollow pen holder and the parametric creative hollow lampshade were respectively completed. The traditional craftsmanship is integrated into the modern manufacturing process with innovative techniques, and the Chinese cultural spirit and beauty of nature are successfully connected.

The art of weaving is an ancient and beautiful technique that never fades. Various weaving techniques and various totem patterns contain rich cultural connotations. The development of cultural and creative industries often uses existing environmental materials to deconstruct and use them in innovative ways to reinspire and present another style. With the rapid progress of computer-aided design technology, digital applications in the design practice has become an important element, and parametric design is the best popular design method in recent years. This paper is mainly in view of the weaving crafts in the traditional culture of the world occupies an important role, and the precious traditional weaving crafts gradually lost. Therefore, it is planned to construct a 3D model with knitting characteristics through a parametric design method, and print out the prototype through the 3D printing mechanism, that is, the traditional craftsmanship is integrated into the modern manufacturing process with innovative techniques, to show the new style of this weaving craft culture that is different from the past, so that it not only retain its inherent spirit, but also can promote this ideal of cultural creativity.

The Visual Basic program of standard straight bevel gear’s parametric design based on Solidworks software was completed. The geometric features of bevel gears were analyzed, parametric design variables were defined, each control point was determined in Cartesian Coordinate System. In development of the system, the API functions such as CreatLine, FeatureRevolve,FeatureCut, CreatePlaneAtAngle3, InsertCutBlend and FeatureCircularPattern were used;the involute profiles of bevel gear at large end were fit by splines. The parametric design of bevel gears may provide a basis for further finite element stress analysis or assembly.
