    Notes: In the process of products design, most input information for Quality FunctionDeployment always possess the characteristics of fuzziness and language, so, various inputinformation of house of quality are regarded as language variable, glossary convene of fuzzylanguage and fuzzy numeral. The main idea of modeling of fuzzy information with house of quality isexplained in detail, and fuzzy integrating of custom needs and fuzzy modeling of products planningwith HOQ are proposed. Thus, the fuzzy or qualitative information can be dealt with efficiently, andthe significative decision in fuzzy circumstance can be made

    Notes: With the development of science and technology, harmonious design will be one of thelatest trends in modern mechanical products development. Based on the harmonious design method,the well synthesized quality products will be invented. It will have little negative influence on societyand the natural environment, and the high utilization rate of resources and the most comprehensivebenefits in the full lifecycle from planning, designing, manufacturing, packaging, and discarded. Theharmonious state can be obtained between products with political, economic, cultural, legal,scientific, natural and social environments. The harmonious design is investigated from the harmonyof design methods; the harmony of product function with performance; and the harmony of productwith product, with human, with technology, with society environment and with natural environment.And the evaluation of harmonious degree and management system are studied in this work, too. Basedon system engineering and economic, cultural, legal, scientific, natural and social environmentfactors, the formula of the complete system of products design is established. Therefore, the newvitality and higher market competitiveness of product can be achieved. Not only the design is forhuman but also for nature, for the harmony of human and nature

    Notes: Part manufacturability under Concurrent Engineering (CE) environment was analyzed indetail. An evaluation system of Design For Manufacturing (DFM) was proposed according to CEideas. The evaluation methods for part manufacturability feature-based are intended to present inthis paper. Product design can be guided according to feedback information by evaluating the partmanufacturability. Finally an example of rabbet-feature manufacturability of a turbine blade wasgiven to show the method available and practicable

    Diagnosis of Local Fault and Identification of Transient Fault Force in Rotating Machinery (2005)

    Notes: Model based fault identification techniques can be used to diagnose local faults in rotating machinery; the equivalent loads that represent fault forces can be used to identify the fault location. But in some cases the equivalent loads smeared over many nodes, and make it hard to identify accurate fault location and transient fault force. In this paper, the fault location is identified using least squares fitting approach by the system’s vibration shape when the fault signal is periodic or quasi-periodic. And after the fault location is ascertained, the transient fault forces can be identified by transient residual vibration using simple matrix multiplications and additions. Numerical simulations and experiment on rotor to stator rub are used to test the method, which proved the efficiency of the method

    Notes: A two-dimensional cellular automaton (CA) model is developed to simulate damage andfracture morphology evolution on the mesoscale in materials. The plastic convection of damage ismapped onto the CA lattice, and initiation, propagation and coalescence of damage are simulatedwith a local rule-based scheme of a probability cellular automaton. The model includes knownphysical distinctions of fracture behavior between microcracks and microvoids, and they arecharacterized by modifying the probability rule of the cellular automaton. The simulations providevisual insight to understand how those physical processes dynamically progress and they affect thedamage evolution in materials. The modeling can be used to link micromechanical models tocontinuum damage models

    Notes: This paper presents mainly the nonlinear dynamics of the mechanical system withsectional frictions and combination friction coefficients. It is clear that the nonlinear dynamiccharacteristics of mechanical systems with sectional frictions are quite different from those ofclassical machinery, and have more precise and valuable in many practical projects. Theexpressions of various nonlinear forces are given firstly and the approximation solutions of thesystem are found with asymptotic method in nonlinear theory, and the combination frictioncoefficients and damping coefficients of the materials are obtained. Then some nonlinear dynamiccharacteristics of the system with sectional frictions are also discussed. The results are veryimportant for designers of these machines

    Notes: Vibratory pile driver-extractor is broadly applied in civil constructions, but the frictionvibration theory and dynamic characteristics of friction vibration are not studied well. In this paper,the vibration friction characteristics and dynamics of pile driving process are studied based onnonlinear dynamics and friction theory. A dynamic model of system is established firstly, and thennonlinear dynamic principle and working process are studied in details. The simulation results canprovide useful guidance for both vibration friction research in engineering and design in thedevelopment of such machines
