This paper presents structural studies of a medium scale composite wind turbine blade construction made of epoxy glass fiber for a 750kW rated power stall regulated horizontal axis wind turbine system. The complex geometry of the blade with a skin-spar foam sandwich structure was generated by utilizing commercial code ANSYS finite element package. Dimensions of twist, chord and thickness were developed by computer program. NREL S-series airfoils with different chord thickness are used along current blade cross-sections. The current design method uses blade element momentum (BEM) theory to complete satisfactory blade design and can be carried out using a spreadsheet, lift and drag curves for the chosen aerofoil. According to composite laminate theory and finite element method, optimal blade design was obtained. The focus is on the structural static strength of wind turbine blades loaded in flap-wise direction and methods for optimizing the blade cross-section to improve structural reliability. Moreover, the natural frequencies and modal shapes of the rotor blade were calculated for defining dynamic characteristics. Structural analysis was performed by using the finite element method in order to evaluate and confirm the blade to be sound and stable under various load conditions.

It has considerably practical significance to apply Man-Machine-Environment System Engineering (MMESE) on large scale vessel throughout its whole life cycle. At present, there are not too many researches on this topic in China, but specific tasks refer to a really wide range while developing separately without guidance from the very top. From the views of vessel system, life cycle system of it and MMESE discipline system, the MMESE application system for vessel is constructed; based on it and System Engineering, the three dimension application model for vessel throughout its life cycle is brought forth; based on it and Concurrent Engineering, the concept and framework of MMESE Application System Engineering throughout Life Cycle of Large Scale Vessel (MLM) is finally developed, which plays an important role in conducting actual projects. © 2014 Trans Tech Publications, Switzerland.

In order to enhance ideality of innovation by comprehensive application of all aspects which affect ideality, we propose a framework which embeds the theory of constraints and TRIZ into the customer domain, function domain and physical domain of axiomatic design. The dataflow is described from customer domian to physical domain through function domain in this framework, and a case study is used to shown the validation.

Network-based collaborative product development has become a trend in manufacturing industry, which depends on two key information technology: the Semantic Web and the standard for the exchange of product model data (STEP). EXPRESS is the STEP product data modeling language, and OWL is the standard ontology representing language used in the Semantic Web. Only when the EXPRESS models are converted to OWL models, product information can be exchanged at the Web. The ontology meta-modeling theory was employed to analysis the ontology definition metamodel of EXPRESS and OWL, in order to build up the mapping relationship between them. A formal EXPRESS-to-OWL mapping algorithm is then proposed, represented by abstract syntax.

To solve the permutation flowshop problem more effectively, a novel artificial immune particle swarm optimization (PSO) algorithm has been proposed. The new algorithm combined the biology immune system theory with particle swarm algorithm by the following phases. Firstly, the scheduling objective and constrain condition were served as antibodies while solutions was served as antigens. Secondly, the particles were encoded as workpiece processing sequence. Furthermore, a concentration selection strategy was adopted to maintain the particle diversity. Finally, comparing with genetic algorithm and PSO, case results showed that immune PSO algorithm not only optimized results and convergence velocity but also had a small fluctuation.

Modular design technology is one of the ways to realize the product variety. It has been widely used in increasing fields. Module partition which has been the hot spot in and around the world is the key part of modular technology. In this paper, the combination of system clustering and the fuzzy ISODATA algorithm is used to achieve the rough-to-fine division according to the principles of module partition. Finally, the automobile security system has been taken as a case to justify the validity of the method and the result of the division accorded with the function of it.

The operating accuracy of the tractor driver directly affects the transportation efficiency and the airport security. The research of the human reliability is an important way to measure task performance and reduce errors. The main content of the study is to analyze the reliability of the driver of the towbarless tractor in Harbin International Airport. The task network is established using the method of HTN according to the towing actions. The reliabilities of each operation are calculated with the methods such as HCR and the characteristics of human behaviour (SOR). The simulation model is run for a hundred thousand times on the platform of the discrete event simulation software QUEST, and conclusions are brought out, one of them is the reliability of the driver is 99.666%. The main causes of the human error are the qualification and driving experience of the drivers and the circumstance of the airport. © (2012) Trans Tech Publications, Switzerland.

Aiming at the characteristics of optional disassembly problem, disassembly strategy based on bionic disassembly hive model is presented in this study. This method is combined with modular theory to resolve the data explosion which is caused by too many parts in disassembly body for relevant algorithms. Through establishing disassembly hive space model, the judgment of disassembly direction and some other problems are transferred into the evaluation of ant bee groups' migration routes. The relative disassembly difficulty of the part is defined based on the conception of disassembly ring. And new ideas of obtaining disassembly sequence are introduced to improve the efficiency of getting disassembly programs. © (2011) Trans Tech Publications.

Modular design is a key technique of mass customization. The relationship between the module interfaces is the basis of modular design, and it is essential to study the model and the application of the relationship between the module interfaces. Based on the Matter-element model of the Extenics, the models of the module, module interfaces and the relationship between module interfaces were established. Combining with the Boolean matrix of the module interfaces relationship, the application of the model was discussed.

Applying man-machine-environment system engineering (MMESE) in vessels is a method to improve the effectiveness of the interaction between equipment, environment, and humans for the purpose of advancing operating efficiency, performance, safety, and habitability of a vessel and its subsystems. In the following research, the life cycle of vessels was divided into 9 phases, and 15 research subjects were also identified from among these phases. The 15 subjects were systemized, and then the man-machine-environment engineering system application model for vessels was developed using the ICAM definition method 0 (IDEF0), which is a systematical modeling method. This system model bridges the gap between the data and information flow of every two associated subjects with the major basic research methods and approaches included, which brings the formerly relatively independent subjects together as a whole. The application of this systematic model should facilitate the application of man-machine-environment system engineering in vessels, especially at the conceptual and embodiment design phases. The managers and designers can deal with detailed tasks quickly and efficiently while reducing repetitive work. © 2011 Harbin Engineering University and Springer-Verlag Berlin Heidelberg.
