The increasing complexity of modern industrial systems calls for automatic and innovative predictive maintenance techniques. As suggested by the Industry 4.0 process, this demand translates in the need of more-intelligent drives. Herein, the use of a special kind of neural networks to interpret the data from motor currents for diagnostic purposes is described. The early detection of possible faults in the electrical motor allows programmed maintenance and reduces the risk of unplanned shutdowns. The innovation is in the overall approach to the neural network training, which does not call anymore for a large set of faulty motors. A large training dataset generated using a combination of tuned motor models and some data augmentation techniques is proposed. The result is a comprehensive and effective motor condition monitoring algorithm, whose hearth is a convolutionary neural network trained by a safe and cheap simulation-based dataset. The details of the design are fully reported here. The method has been implemented in the laboratory and fully tested on both healthy and faulty permanent magnet synchronous motors. The generality of the proposed method also paves the way for the detection of other failures and the application to different electrical motors.

In recent years the increased use of 3D scanning hardware has introduced a new type of data to the design and manufacturing field. In many design and manufacturing applications (e.g., part refurbishing or remanufacturing) a scanned 3D model may be provided as an input to a shape matching system to search the database for related or identical models with the purpose of extracting useful information. The introduction of scanned 3D models restricts the use of the CAD-based 3D model search and comparison methods due to significant differences in model representations. The CAD models provide structured and high-level representation of the part features, whereas the scanned 3D models usually come in a polygonal mesh representation, which does not directly reveal engineering features of the part. These differences require new algorithms for comparing the shapes of scanned 3D models, ones that are robust against different scanning technologies and can be adjusted to work with different representations of the models. In this paper a new approach and algorithms for scanned 3D shape matching and comparison are presented. Given the scanned 3D model as an input the approach first uses general-purpose shape matching methods to identify a small list of likely matches (i.e., candidate models) for more detailed shape comparison. To perform detailed comparison of the shapes each candidate model is geometrically adjusted (i.e., rotated and translated) with the input using one of two new viewpoint algorithms developed in this paper Once the candidate models are adjusted they are compared to the input to identify the similarities and differences between their shapes. To accomplish this task a new 3D shape matching algorithm is developed. The relevance of the methodology developed in this paper is illustrated with the application of scanned 3D shape matching and comparison algorithms in rapid manufacturing of broken parts.

Industrial product-service systems (IPS2) are an increasingly important and profitable offering of manufacturing companies. Alongside specific design processes, the suitable integration of the customer and all other stakeholders is essential for the market success of IPS2. In this context, a multitude of methods and processes have been published to date. The novel approach of this contribution consists in the consideration of the individuality of the design object and of the corresponding design process. Presented results are (i) a workshop-based procedure to analyse the design object including the goals and risks as well as the basic conditions of the stakeholder integration, (ii) a procedure to plan an individualised stakeholder integration process based on the analysis results and a collection and systematisation of 35 methods for customer integration, and finally, (iii) a condensed version of the approach which allows to apply the procedure on short notice. This work is based on a comprehensive literature research as well as on the results of three case studies.

In celebration of the 10th anniversary of the Journal of computing and Information Science in engineering this article will provide a retrospective of past research on intelligent systems in engineering design research, and new perspectives. Intelligent systems and expert design knowledge have become important and integral parts of systems that support product design;they are embedded in many CAD tools, design knowledge repositories, design assistants, and design critics. Such tools have become common place for assisting designers in creating new designs, modifying old ones, or storing expert design knowledge for later use by oneself, other designers or future generations. Intelligent systems are becoming increasingly important as computer technologies have matured, and global competition has demanded increasingly better products, faster. As these trends continue, intelligent systems will be increasingly necessary for competitiveness. This retrospective will present past advances in a range of areas from model-based and case-based reasoning, machine learning, biologically inspired design, creative design, and virtual design. The work described has roots in many disciplines including engineering, artificial intelligence, psychology, human factors and management science. We present this work with an aim to identify directions in which the field is moving, and more importantly, to gain insights into future directions and critical areas for future research investments.

Graph-Based Design Languages: A Lingua Franca for Product Design Including Abstract Geometry

引用

IEEE COMPUTER GRAPHICS AND APPLICATIONS 2016年第5期36卷 88-93页

作者： Schmidt, Jens Rudolph, Stephan IILS Delhi India Univ Stuttgart Inst Stat & Dynam Aerosp Struct ISD Similar Mech Grp Stuttgart Germany

Product engineering involves designing and dimensioning a product, including geometric modeling and scientific simulation and analysis to fulfill predetermined requirements. Therefore, the engineering design effort requires a multidisciplinary analysis that is based on a multitude of different models, each of which require a different kind of representation of the same product geometry. The proposed approach uses a design language and a design compiler to translate an abstract source geometry in an abstract representation scheme into an arbitrary target format. With this approach, all models are generated automatically and are consistent with each other.

An Analysis of Description Logic Augmented with Domain Rules for the Development of Product Models

The languages and logical formalisms developed by information scientists and logicians concentrate on the theory of languages and logical theorem proving. These languages, when used by domain experts to represent their domain of discourse, most often have issues related to the level of expressiveness and need specific extensions. In this paper, we first analyze the requirements for the development of structured knowledge representation models for manufacturing products. We then explore how these requirements can be satisfied through the levels of logical formalisms and expressivity of a structured knowledge representation model. We report our analysis of description logic (DL) and domain-specific rules with respect to the requirements by giving an example of a product ontology developed with ontology web language-description logic (OWL) and augmented with semantic web rule language (SWRL) rules. Clearly, increasing the expressivity of a product ontology also improves that of domain-specific rules, but there exits the usual tradeoff between the expressivity of languages and the complexity of their reasoning tasks. We present a case study of an electromechanical product to validate the analysis and further show how the OWL-DL reasoner together with the rule engine can enable reasoning about the product ontology. We finally discuss the open issues such as capabilities and limitations related to the usage of DL, OWL, and SWRL for product modeling. [DOI: 10.1115/1.3385794]

Verifying driver performance for heavy haulage fatigue management

引用

IET INTELLIGENT TRANSPORT SYSTEMS 2019年第6期13卷 1033-1040页

Working performance of drivers is an important concern of commercial logistics firms as it directly relates to operational efficiency targets. However, in heavy vehicle activity, the enforcement of fatigue management rules by the Australian government can potentially influence this efficiency as the regulation scheme controls maximum work time and minimum rest time of drivers. Therefore, evaluating a driver's performance in the context of fatigue compliance is an essential need that aims to assist transport operators to increase their operational efficiencies. This research proposes a method in assessing how well a driver performs his job by using anomaly detection principles from intrusion detection systems in network security. This approach utilises output data of the logistics fatigue manager application and compliance outcomes of the fatigue compliance verification system to measure the driver's performance. In addition to performance concerns, the system also monitors safety levels based on fatigue conditions of drivers to ensure that the positive evaluation outcomes can be applied standards for the whole fleet in practice. The results highlight the opportunity to monitor driver fatigue levels for verifying fatigue risk within existing fatigue compliance requirements.

production of Open Cell Aluminum Foams by Using the Dissolution and Sintering Process (DSP)

引用

JOURNAL OF MANUFACTURING SCIENCE AND engineering-TRANSACTIONS OF THE ASME 2009年第4期131卷 041009页

作者： Barletta, M. Gisario, A. Guarino, S. Rubino, G. Univ Roma Tor Vergata Dept Mech Engn I-00133 Rome Italy Univ Roma La Sapienza Dept Mech & Aeronaut I-00184 Rome Italy

The manufacture of open cell metal foams by dissolution and sintering process (DSP) is the matter of the present work. Aluminum foams were produced by mixing together carbamide particles with different mesh sizes (i.e., space-holder) and very fine aluminum powders. Attention was first paid at understanding the leading phenomena of the different stages the manufacturing process gets through: Compaction of the main constituents, space-holder dissolution, and aluminum powders sintering. Then, experimental tests were performed to analyze the influence of several process parameters, namely, carbamide grain size, carbamide wt %, compaction pressure, and compaction speed on the overall mechanical performance of the aluminum foams. Meaningfulness of each operational parameter was assessed by analysis of variance. Metal foams were found to be particularly sensitive to changes in compaction pressure, exhibiting their best performances for values not higher than 400 MPa. Neural network solutions were used to model the DSP. Radial basis function (RBF) neural network trained with back propagation algorithm was found to be the fittest model. Genetic algorithm (GA) was developed to improve the capability of the RBF network in modeling the available experimental data, leading to very low overall errors. Accordingly, RBF network with GA forms the basis for the development of an accurate and versatile prediction model of the DSP, hence becoming a useful support tool for the purposes of process automation and control.
