In this paper, our aim is to design and built a lightweight single-piston floating caliper, without compromising the performance. The aim is to design a caliper as simple as possible so that the manufacturing cost would be low. Mounting position can also be varied in this design. To make the caliper lighter it is necessary to remove material, Aluminium 7075 is used as the material, and Asbestos is taken as the brake pad material. To maintain the stiffness the material has to be used in a more efficient way. A computer-aided design model of a brake caliper is created in Solidworks and analyzed for stress and deformation in ANSYS Workbench.

Graphene Membranes

For both polyimide membranes in aerospace and graphene membranes in nanoelectronics with surface accuracy requirements, wrinkles due to the extreme out-of-plane flexibility yield inverse influences on the properties and applications of membranes. In this study, on the basis of discrete topology optimization, we propose a prenecking strategy by adopting elliptical free edges to suppress the stretch-induced wrinkling. This prenecking strategy with the computer-aided-design (CAD)-ready format is versatile to eliminate wrinkles in stretched membranes with clamped ends and achieve wrinkle-free performances. The wrinkle-free capability of the prenecking strategy, capable of satisfying the shape accuracy requirements, indicates that by suffering insignificant area loss, concerning of wrinkling problems in membranes is no further required. As compared with the existing researches focusing on studying wrinkling behaviors, the prenecking strategy offers a promising solution to the stretch-induced wrinkling problem by eliminating wrinkles through design optimization.

The conceptual design model for mechanical product and its computer aided design are the important and focus problems. A mechanical product design process of FPBS model, function-principle-behavior-structure model, was put forward and discussed. The semantic relationships between the elements of FPBS model were studied to make foundation for the application of FPBS model. The operational demand of knowledge system for FPBS model was analyzed, and indicates the ontology can be applied effectively to knowledge system operation of FPBS model. Then, an ontology based FPBS model was established and a FPBS ontology model system was constructed. The experimental results indicate the model can be used in computer aided conceptual design for mechanical product effectively.

Rapid prototyping uses layered manufacturing technology to produce functional parts directly from 3D computer-aided design model without involving any tools and human intervention. Due to layer by layer deposition, volumetric error remains in the part which is basically the volumetric difference between computer-aided design model and the fabricated part. This volumetric error causes poor dimensional accuracy and surface finish, which has limited the widespread applications of rapid prototyping. Although rapid prototyping is able to produce functional parts in less build time with less material wastage, today many industries are looking for better surface quality associated with these parts. Literature discloses that the part quality can be improved by selecting proper build orientation that corresponds to minimum volumetric error. In support of this, current study presents a computer-aided design-based novel methodology to precisely measure the volumetric error in layered manufacturing process, in particular fused deposition modeling process. The proposed method accepts computer-aided design model of the part in .CAT format and automatically calculates volumetric error for different build orientations. An Excel function is integrated with it to determine optimum build orientation based on minimum volumetric error. Several simple and complex examples verified the robustness of our proposed methodology. We anticipate that the current invention will help future rapid prototyping users in producing high-quality products through an intelligent process planning.
