    Notes: So far the literature on inverse shape design in aerodynamics is still confined to the single-point (nominal design point) design and to steady flow. This situation cannot cope with the modern development of internal and external aerodynamics and aerothermoelasticity, especially turbomachinery and aircraft flows. Accordingly, in recent years a new generation of inverse shape design problem has been suggested and investigated theoretically and computationally, consisting mainly of: unsteady inverse and hybrid problems; multipoint inverse and hybrid problems; and inverse problem in aerothermoelasticity. It opens a new area of research in fluid mechanics and aerothermoelasticity. An overview of its status and perspective is given herein, emphasizing the new concepts, theory and methods of solution involved.

    Multipoint inverse shape design of airfoils based on variable-domain variational principle (2004)

    Notes: As a kind of free (unknown) boundary problems, inverse shape design of airfoils attracts extensive attention in recent years. By variable-domain variational theory, free boundary condition can be coupled with the governing equations for flow field, which makes it possible to calculate the flow field with the free boundary simultaneously. In this paper, the variational principle (VP) of 2D airfoil shape design problem is obtained from the basic dimensionless velocity potential equations for 2D compressible flow by using systematic approach and variable-domain variational formula. The deformable finite element method based on the VP is used to segmentally design airfoil at two design points (angles of attack) and four design points, respectively. The results show that the present method is highly effective and accurate to solve multipoint inverse problem of airfoils.

    Notes: In the frame of shock-induced depoling, PZT 95/5 ferroelectric ceramics with niobium dopedhas been assembled for the pulsed power supply, and the electrical current output has been investigatedunder the action of shock wave in a "normal mode". The electrical response of LRC load especially for thesmall resistance (R) and small inductance (L) load was studied. Plane-shock-wave tests were conducted,and the PZT 95/5 ceramics stacked in parallel were devised to generate high-power electrical pulse. Anoutput current of 7 kA has been obtained, and the corresponding rise time of the front edge is under 500ns. Theoretical calculations were conducted and a good agreement with the experiment presented

    Research on Innovative Product Design System Based on QFD and TRIZ (2006)
    s.l. ; Stafa-Zurich, Switzerland
    Materials science forum Vol. 532-533 (Dec. 2006), p. 1144-1147

    ISSN: 1662-9752

    Notes: This paper presents an innovative product design system based on Quality FunctionDevelopment (QFD) and Theory of Inventive Problem Solving (TRIZ in Russian abbreviation).House of Quality (HOQ) is the core of QFD. To make QFD more practical and operable for smalland medium-sized companies, a simplified model of HOQ is proposed. A set of reasoning schemefor inferring requirements relationships is adopted to facilitate constructing the HOQ. Thecontradiction in the process of mechanical design is defined by TRIZ as physical contradiction andtechnical contradiction. These two contradictions are solved through contradiction matrix andinventive principles of TRIZ. The innovative design system mainly uses the tool of contradictionmatrix to solve the bottle techniques attained from QFD. By taking the HOQ as its interface theintegration between QFD and TRIZ is realized. After conducting quality function development, twooutputs can be obtained. They are the technical measure needing improvement and the technicalmeasure that is getting worse while improving the former one. These two measures are taken asinputs of TRIZ module to analyze and solve the problem of product design
