Oriented Approach

Abstract Laboratory of Machine Design at the University of Oulu has modelled the production information for a gear transmission unit in co-operation with a Finnish gear manufacturer, Santasalo Ltd. The basic idea was to integrate computer aided design into modern FMS-based production activities. The main goal in this project is to capture the whole gear box development process from customer requirements to manufacturable assembly and detail information in OOA models.

Object Oriented Languages

Abstract The need for superior design tools has lead to the development of better and more complex computer aided design programs. Two of the more important new developments in application tools being investigation are Object Oriented Languages, and HyperMedia. Object Oriented Languages allow the development of CAD tools where the parts being designed and the design procedures specified are conceptualized as objects. This allows for the development of design aids that are non-procedural and more readily manipulated by the user trying to accomplish a design task. HyperMedia allows for the easy inclusion of many different types of data, such as design charts and graphs, into the tool that are normally difficult to include in design tools programmed with more conventional programming languages. This paper explores the development of a computer aided design tool for the design of a single stage gear box using the development HyperCard® environment and the HyperTalk® programming language. The resulting program provides a user friendly interface, the ability to handle several kinds of design information including graphic and textual, and a non-procedural design tool to help the user design simple, one stage gear boxes. Help facilities in the program make it suitable for undergraduate instruction in a machine elements design course.

The Relationship

Feature is one of the methods for representing objects from which are representing components, products and processes. This article presents methods for integration of features of methods in modeling and analysis of composite structural components. The aim of the research is to develop methods for verification and validation of composite layered structure, distinguishing components of the individual layers and identify the relationship between them. By applying the method of features it is possible to determine the structure of the composite fit to the requirements of design and construction. Proposed new types of feature, which allows the creation of object-oriented structures of composite components.

This paper describes three approaches for virtual product development of plastic injection moulds. The first is characterized by the use of three-dimensional computer aided design (CAD) for product design, two-dimensional drafting for mould design and three-dimensional computer aided design/manufacture (CAD/CAM) for mould manufacture. The second is characterized by the use of three-dimensional CAD models by all three participants, but between any two participants some form of file conversion is normally required because different CAD systems are used. The first two approaches share one common feature: the models are passed serially from the product designer to the mould designer and on to the toolmaker. They represent current practice in industry. The third approach is a proposed collaborative design process. Participants can work concurrently on the same model, sharing their knowledge and experience. The process is currently being refined and will be validated later this year with a prototype system based on Unigraphics iMAN software.

Background: The perineum area that interacts with the saddle is vulnerable; compressing neurovascular tissues has been asserted as the link of pathologies. Existing saddle designs are mainly based on the hole blocks, which are composed of two materials. These composite combined structures increase manufacturing difficulty Objective: The injection molding technology is suitable for mass production. We proposed a saddle design to meet the ergonomic requirements of cyclists. Saddle frames present a continuous curvature geometry to ensure a improved injection modeling. Methods: Static numerical calculations and measurements were employed for vertical load evaluations; with different stiffness regions acquired using perforated chain patterns. Two-step plastic injection molding was utilized with proper bonding and processing compatibility. In prototyping, the first and second shots are PC and TPE, respectively Results: The frame sustains vertical loadings from bending and provides adequate stiffness and proper flexibility. The computer-aided design mold increases the contact area, and annular grooves increase the adhesion between two materials. The outer frame exhibits high rigidity; the middle area exhibits flexibility and high deformation. Conclusion: This question is widely noticed and various answers were proposed. By investigating the patent database and searching journal papers on saddle designs, the authors confirmed the novelty of the proposed structure.
