This paper proposes the design reuse model of complex product which is integrated with CBR (Case-Based Reasoning) and is established under virtual manufacturing environment. This model is aimed at the issue how to rapidly extract reuse design knowledge and select matching reuse design model to ensure that complex product can quickly respond to customers’ diverse and personalized demands with low costs during designing and manufacturing complex products. This model makes reasonable planning for the existing case design and considers the usability and economy during product design comprehensively. And on this basis, this paper researches the reuse design strategy ensuring the rapid response of complex product and the method of reuse process, develops the design system basing on case reuse technology and achieves the rapid design and analysis of product. Besides, the proposed design reuse approach is going to be tested by integrating with the farm dump truck produced by one certain machinery Co., Ltd.

In order to accurately guide on-site workers to quickly accomplish the assembly job of complex products, and reduce the deployment cost of assembly instruction, we propose a publishing method of lightweight 3D assembly instruction for complex products. In this paper, the key frames of assembly motion and the 3D technical annotations in the lightweight model are mapped to the time-based assembly process. Then, the annotated lightweight model and assembly process information are integrated and published into a single 3D assembly instruction document. An assembly instruction publishing example of satellite antenna feed component shows that the lightweight 3D assembly instruction is well instructive and affordable because it provides the interactive simulation of assembly process and time-based display of assembly technical annotations without using expensive computer-aided design (CAD) systems, graphics workstations, or virtual reality equipments. This method gives a full play to the advantages of model-based definition technology and lightweight model, and fills the gap between the process planning and the instruction publishing in the 3D virtual manufacturing environment.

Rapid Design

Because of a few characteristics of complex product, such as the variety of its components, and the structural complexity and so on, the realization of the rapid design of complex product requires combination of a variety of theories and methods that support product’s rapid design. Therefore, this study assesses complex products and puts forward a new rapid design method based on general structure model and reusable parts resource. First of all, the characteristics and implementation process of this method is summarized. Then, the general structure model of the complex product family is established on the basis of modular thoughts, and the definitions of the four vari-size grained abstract concepts are discussed in this model as well as its semantic relationships. The configuration design of the complex products is based on this general structural model, and with the increase of networked product design information, and more and more manufacturing enterprises have built up their own web-based component repositories to store those detailed design information. On account of those, the rapid design process of the complex product is introduced, with configuration design and reusable parts resource as the core. Lastly, an application example (i.e. the conventional beam pumping unit) is presented to verify the feasibility of which has been discussed above.

Aided Design

Computer-aided design of assembly processes (Computer aided assembly planning, CAAP) of complex products is an important and urgent problem of state-of-the-art information technologies. Intensive research on CAAP has been underway since the 1980s. Meanwhile, specialized design systems were created to provide synthesis of assembly plans and product decompositions into assembly units. Such systems as ASPE, RAPID, XAP / 1, FLAPS, Archimedes, PRELEIDES, HAP, etc. can be given, as an example. These experimental developments did not get widespread use in industry, since they are based on the models of products with limited adequacy and require an expert’s active involvement in preparing initial information. The design tools for the state-of-the-art full-featured CAD/CAM systems (Siemens NX, Dassault CATIA and PTC Creo Elements / Pro), which are designed to provide CAAP, mainly take into account the geometric constraints that the design imposes on design solutions. These systems often synthesize technologically incorrect assembly sequences in which known technological heuristics are violated, for example orderliness in accuracy, consistency with the system of dimension chains, etc.An AssemBL software application package has been developed for a structured analysis of products and a synthesis of assembly plans and decompositions. The AssemBL uses a hyper-graph model of a product that correctly describes coherent and sequential assembly operations and processes. In terms of the hyper-graph model, an assembly operation is described as shrinkage of edge, an assembly plan is a sequence of shrinkages that converts a hyper-graph into the point, and a decomposition of product into assembly units is a hyper-graph partition into sub-graphs.The AssemBL solves the problem of minimizing the number of direct checks for geometric solvability when assembling complex products. This task is posed as a plus-sum two-person game of bicoloured brushing of an ordered set. In the paradigm of this model, the brushing operation is to check a certain structured fragment for solvability by collision detection methods. A rational brushing strategy minimizes the number of such checks.The package is integrated into the Siemens NX 10.0 computer-aided design system. This solution allowed us to combine specialized AssemBL tools with a developed toolkit of one of the most powerful and popular integrated CAD/CAM /CAE systems.

AbstractThis research work presents a methodological support for the specification of complex products. This is achieved by developing a specification structure in a MBSE environment. The new method draws on success factors of complex product specification, principles of MBSE and the explanatory model of PGE – Product Generation Engineering. For evaluation, the method is applied within a student development project. A high applicability and the realization of novel synergies for coping with continuously increasing product complexity is demonstrated.

AbstractWhen does the complex product of a given number of subsets of a group generate the same subgroup as their union? We answer this question in a more general form by introducing HS-stability and characterising the HS-stable involution subsemigroup generated by a subset of a given involution semigroup. We study HS-stability for the special cases of regular $${}^{*}$$ ∗ -semigroups and commutative involution semigroups.

Abstract The fast construction of a Virtual Factory model without using a CAD package can be made possible by using computer vision techniques. In order to create a realistic Virtual Manufacturing environment, especially when such a model has to be created in correlation to an existing facility, a reliable algorithm that extracts 3D models from camera images is needed, and this requires exact knowledge of the camera location when capturing images. In this paper, we describe an approach for depth recovery from 2D images based on tracking a camera within the environment. We also explore the extension of our telemetry-based algorithm to remote facility management, by tracking and synchronizing human motion on the shop floor with motion of an avatar in a Virtual Environment representing the same shop floor.
