A novel approach to modelling and simulating the contact behaviour between a human hand model and a deformable object

Computer Methods in Biomechanics and Biomedical Engineering, 2011

The integration of biomechanical knowledge of human hands into product design process starts to play an increasingly important role in developing an ergonomic product-to-user interface for products and systems requiring high level of comfortable and responsive interactions. Generation of such precise and dynamic models can provide scientific evaluation tools to support product and system development through simulation. This type of support is urgently required in many applications such as hand skill training for surgical operations, ergonomic study of a product or system developed and so forth. The aim of this work is to study the contact behaviour between the operators' hand and a hand-held tool or other similar contacts, by developing a novel and precise nonlinear 3D finite element model of the hand and by investigating the contact behaviour through simulation. The contact behaviour is externalised by solving the problem using the bi-potential method. The human body's biomechanical characteristics, such as hand deformity and structural behaviour, have been fully modelled by implementing anisotropic hyperelastic laws. A case study is given to illustrate the effectiveness of the approach.

Our research concerns the development of a knowledge engineering module integrated in a collaborative eGroupware system. This platform is used by engineers to realise their projects in a collaborative way and in following a defined professional process. The first step of our approach is based on the modelling of the professional process used by professional actor. We have developed a formalism called RIOCK (Role Interaction Organisation Competence and Knowledge) to identify the emanating Knowledge resulting from the interaction between the roles played by professional actors. According to the obtained cartography of Knowledge, we have defined a typology of Knowledge and built an ontology to create a representation language in order to share and broadcast Knowledge. In other hand, the RIOCK models allow us to design a knowledge engineering module based on a multi-agent system. This system monitors the action of the professional actors inside the eGroupware and capitalizes, annotates, and broadcasts Knowledge in using the semantic web technologies and the ontology.

An approach to support the Knowledge Management Process inside professional activities

As a matter of fact, these projects require that engineers, with different specialities, collaborate to carry out the same goal. Inside professional processes, they use their know-how and knowledge in order to achieve the laid down goals. Our approach consists in using an organisational approach to identify the competences and knowledge of professional actors which allows the design and the description of agents’ know-how. Furthermore, the paper describes the design of our agent model based on an organisational approach and the role of a domain ontology called OntoDesign to manage heterogeneous and distributed knowledge.

Using the knowledge configuration model to manage knowledge in configuration for upstream phases of the design process

In these fields, engineers handle a large range of expert models such as computed aided design (CAD) and computed aided engineering (CAE) models which encapsulate parameters and design rules, which are considered as knowledge. This knowledge has to be shared by different users and must remain coherent through the design and simulation activities. This means maintaining consistent parameter values, following design rules, etc.) during product development and especially in the early design stages. Nowadays, faced with the diversity and the increasing number of expert models used at the same time, there is a lack of parameters and design-rule management to keep the knowledge contained within them coherent throughout several design activities. To improve expert model inter-operability there are numerous product models (in UML language) which support the product lifecycle management approach through data and information management throughout the entire product lifecycle. However, these models are not focused on the management of knowledge embedded in CAD and CAE models. In this context we propose a model called the KCModel in UML, to manage the knowledge encapsulated and ensure the coherence, e.g. the same parameter value used in several expert models, through several product design activities in a collaborative engineering context. The KCModel is based on the MDA/MDE (model driven architecture/model driven engineering) approach to managing knowledge in configurations synchronized with CAD and CAE models. This research work and the KCModel come within the scope of a French national project called ADN: “Alliance des Données Numériques” led by the company DPS (specialized in digital product simulation) with the participation of the following companies, amongst others: PSA-Peugeot Citroën, EADS and FAURECIA.

These tools help to share information among business applications. We will prove in this paper the benefit to combine semantic and web services approaches to identify and annotate knowledge in a heterogeneous and distributed information landscape. We present here, a comprehensive explanation of our approach which integrates an intelligent reuse module of knowledge that allows engineers to capitalize their know-how. This knowledge will be extracted by web services that enable communication between several business applications. Then in the second section, we describe different ontologies which are created by users depending on their needs to define knowledge. These are extracted from business applications thanks to semantic web service. At the end, this knowledge will be annotated and saved in a RDF file.

The MAS supports R&D teams to extract and re-use engineering knowledge so as to improve their efficiency in developing new products. Our research targets the development of a knowledge engineering system integrated into a PLM -Product Life cycle Management -environment linked with virtual reality tools. A PLM is a strategic business approach with a consistent set of methodologies and software solutions. It is meant to promote collaborative creation, management, delivery and proper use of this life cycle definition and information product in multinational companies. This system is used by engineers to carry out projects in a collective way while conveying a defined process. The MAS allows capitalization, and to annotate knowledge according to the actions of the designers inside a PLM environment. Then, this knowledge is used by VR tools to analyze various aspects of the virtual prototype such as manufacturing, maintenance, reliability or ergonomics. Consequently, we use expert knowledge to pilot the design process of a virtual prototype inside a three-dimensional immersive virtual reality platform. In this context, our paper describes our knowledge management approach applied to improve ergonomics and collaborative design in industrial areas. (J.-C.

Integrated product–process design becomes more and more complex to manage because of increasingly customized products related to various stakeholders and concerns geographically distributed. It is still represents a huge challenge, especially in the early phases of product development process. In such a context, the management of information within integrated product–process design highlights needs in a consistent engineering model that enables product lifecycle management (PLM) integration. The paper presents a novel multiple viewpoint framework called multiple viewpoint assembly oriented, considering product design and assembly process domains in the broader context of concurrent engineering and PLM. The proposed framework describes the consistency, the propagation of information change, and mechanisms of views generation among the product lifecycle stages in order to support assembly oriented design philosophy. A new modelling language called System Modeling Language is used to describe the proposed model from a systems engineering point of view. The implementation of the model in a Web-service called PEGASUS as an application for PLM systems is described.

Within the context of a design project, the present work therefore describes the studies and ergonomic analyses that can be undertaken during each phase of the design process from a design model based on concurrent engineering. Encompassing the design of the driving cabin of the new generation of high-speed trains (TGV-NG), this paper, through the ergonomic study of a number of technical sub-systems of this product, illustrates the advisory role of the ergonomist who, within the collective design process, ensures that the specific nature of the ''human factor'' is fully integrated into the design approach. Thus, throughout the design process, the ergonomist is called upon both to advise the designer on the characteristics of the target users and, on the basis of a ''desirable future activities'' approach, to help him or her assess the consequences of the design choices made. Ergonomics is described consequently, as an innovation and safety factor. # Safety Science 41 www.elsevier.com/locate/ssci 0925-7535/02/$ -see front matter # 2002 Elsevier Science Ltd.

Design tasks involve many actors and experts throughout the product lifecycle, which starts with product requirements / functional specification / product modelling / manufacturing and ends with its destruction or recycling. Software supporting collaborative design, such as PLM (Product Lifecycle Management) systems, is needed to help design team members in their project tasks. ACSP platform is a web-based PLM system. It supports the design team members in carrying out collaborative activities in product-process-design projects. An improvement of the ACSP platform has been proposed by introducing multi-agent systems at several levels of the ACSP architecture. This improvement is based on the RIO methodology and on many FIPA specifications. With implementation Multi-Agent Systems (MAS) for content and knowledge management in collaborative engineering, one can develop autonomy, reactivity, pro-activity and social ability in the Man-Machine relationships.

Finite element approach applied to human digital model for biomechanical modeling

Human doings undergo simulation thanks to our MANERCOS human digital model. However, it fails to show us overall biomechanics implications because its simulation functions are unable to assess biomechanical parameters as stress and strain levels. Finite element modeling of a human body with its organs, bones, muscles, ligaments and tendons answers to this issue. Our objective is to develop and integrate such a modeling approach into MANERCOS ergonomics software by using the FER finite element code. We have carried out a geometric model and a mesh network device thanks to MANERCOS geometric data. The human body characteristics, considering a mechanical point of view, have been modeled by implementing anisotropic hyperelastic behaviour laws.

We shall describe the chosen methodology used and in particular the combined assessments of some fields of desirable future activity. The interface concept used was designed and developed by a multidisciplinary group structured in accordance with concurrent engineering and user centred design principles. The results obtained emphasize the suitability of the method and the necessity of clarifying the emergence of the modification of user strategies, together with the improvement of expertise during empirical evaluations, especially if the product developed has an important impact on a complex socio-technical system.

Current industrial practices in product data management and manufacturing process management systems require better efficiency, flexibility, and sensitivity in managing product information at various levels of abstraction throughout its lifecycle. The aim of the proposed work is to manage vital yet complex and inherent product relationship information to enable concurrent product design and assembly sequence planning. Indeed, the definition of the product with its assembly sequence requires the management and the understanding of the numerous product relationships, ensuring consistency between the product and its components. This main objective stresses the relational design paradigm by focusing on product relationships along its lifecycle. This paper gives the detailed description of the background and models which highlight the need for a more efficient PLM approach. The proposed theoretical approach is then described in detail. A separate paper will focus on the implementation of the proposed approach in a PLM-based application, and an in-depth case study to evaluate the implementation of the novel approach will also be given.

Our researches concerns the development of a MAS associated to e-Groupware in order to build project memories. In SMEs, the development of a product requires a multidisciplinary team where professional actors work together to achieve the same goal. In this collaborative world we observe many exchanges (engineering data, report...) and interactions (meetings, decisions...). Each of these types of communication is at the origin of the emergent knowledge. Consequently we propose an approach based upon the modelling of activities with an organizational meta-model and the use of MAS to trace knowledge and automatically build project memories.
