Based on the analysis of product model characteristics of multidisciplinary collaborative design (MCD), multiple views model expressed by an extended object-oriented method is introduced to satisfy the requirements of different discipline designers for product information interaction and share. A product modeling system for multidisciplinary collaborative design is proposed, and the modeling method of discipline view model under the network environment is given, which can effectively support the evolution of product model and improve the flexibility of product modeling. The clutch is illustrated to validate the proposed methods.

A challenge in effective sharing of product information in collaborative design is the lack of explicit and compatible semantics in the product digital content. Substantial difficulties arise in understanding and interpreting the intended meaning of product data across collaborating design teams and applications. This paper presents a method to capture design semantics with product models for more consistent representation, understanding and interpretation of data semantics to support heterogeneous information sharing. The method incorporates the STEP based interoperability standard, ontology engineering, and object-oriented product modeling to capture and share the semantically interoperable product information. It focuses on: modeling of product data with additional semantics in object-based representations; extension of STEP with supplementary design information; domain ontology development; and semantics-driven schema mapping. A software prototype has been implemented to validate the method and tested with case studies.

Shared Information

In order to meet the requirements of product information sharing and exchange in collaborative design, a design model sharing method was put forward for multidisciplinary domains cooperation. The creation and release mechanism of shared information model were represented. A collaborative product design framework was established based on the sharing model. An application sharing mode of message-driven design was achieved in which information expression approach is built by XML. So packaging and transmission of the shared design information were implemented in collaborative process. An effective solution of information interaction interdisciplinary domains was proposed for collaborative design process.

Multiple Levels

A new product modeling method for product multidisciplinary collaborative design (MCD) is put forward. The method uses a flexible product model which can be extended transversely and lengthwise by multiple levels’ inheritance and new attribute classes’ addition and a class inheritance mechanism under network environment which allows each discipline to build own view model of a product. An open and flexible system architecture supporting the product MCD effectively is put forward, and prototype system implementation is introduced.

Improved Accuracy

The production procedure of ship's hull plates includes hull modeling, lofting, cutting, and forming in sequence. Each process is isolated from the point of view of information flow and current practices in forming hull pieces are experience-dependent. This, in turn, reduces productivity and prevents the development of automation. To satisfy shipyards' demand for improved accuracy and enhanced productivity with mechanization or automation, it is necessary to collect production information, and to structure and maintain it in a well-organized manner. The objective of this paper is to propose an information model for ship's hull piece forming in a systematic manner. First, current shipyardsi practices and information flow relative to hull production process are described. From the point of view of information integration, the necessity of an information model is clarified. An information model for ship's hull piece forming is then proposed. For the information model, product model and concurrent engineering concepts are introduced. Since the construction of the information model with the two concepts requires an object-oriented approach, a new mixed-type, called here ‘hybrid’, object-oriented methodology for hull piece information model is defined. Based on the proposed methodology, the object association and operation analyses are carried out for the information modeling of hull piece forming. Through the analysis, the object-relation diagram shows that kinematics data is indispensable to construct the information model for hull piece forming.

Starting Point

The importance of the concept development phase in product development is contradictory to the level and amount of current computer-based support for it, especially with regards to mechanical design. Paper-based methods for conceptual design offer a far greater level of maturity and familiarity than current computational methods. Engineers usually work with software designed to address only a single stage of the concept design phase, such as requirements management tools. Integration with software covering other stages, e.g. functional modeling, is generally poor. Using the requirements for concept models outlined in the VDI 2221 guideline for systematic product development as a starting point, the authors propose an integrated product model constructed using the Systems Modeling Language (SysML) that moves beyond geometry to integrate all necessary aspects for conceptual design. These include requirements, functions and function structures, working principles and their structures as well as physical effects. In order to explore the applicability of SysML for mechanical design, a case study on the design of a passenger car’s luggage compartment cover is presented. The case study shows that many different SysML diagram types are suitable for formal modeling in mechanical concept design, though they were originally defined for software and control system development. It is then proposed that the creation and use of libraries defining generic as well as more complicated templates raises efficiency in modeling. The use of diagrams and their semantics for conceptual modeling make SysML a strong candidate for integrated product modeling of mechanical as well as mechatronic systems.
