Development and Application of Computer Aided Roll Design System for Thread-steel-bar

Roll pass design is one of the important content of making the rolling technology of section steel.The traditional pass design relies mainly on artificial experience,which brings some tedious calculation and great consumption of raw materials.In order to improve production efficiency,the constitute and the design methods of the roll system for thread-steel-bar are analyzed during stretching,further rolling and finished rolling.The mathematical models and the(experience) formulas used for the roll design in the past are revised.The computer aided roll design system is developed for thread-steelbar based on the structural means of compiling program.The authors adopt Visual Basic6.0 as a visual program tool,and combine the basic design theory of the thread-steel-bar's roll and the practical experience.The system can shorten the design cycle of the new product development,and reduce the energy consumption of the rolling mill and the distribution of production.

Computer Aided Analysis Tool for Building Energy Efficiency in Conceptual Design Stage

Conceptual design is one of the most important stages in building design, and energy efficiency analysis is one of the key issues in building conceptual design stage. The existing energy efficiency analysis methods and tools require inputing large number of parameters. However, the detail information of most parameters is not identified at the stage of conceptual design. And the current prevailing energy consumption simulation methods and tools are not appropriate at the stage of conceptual design. The proposed method can be used to compare the energy efficiency of multi strategies at the conceptual design phase. Minimum data were required to be input for achieving the optimal building design scheme. The method can provide a solution to the gap between the rapid building design cycle and the sustainable development demand in China.

Application of Fractals in Architectural Shape Design

A computer aided method for architectural shape design was developed based on the L systems algorithm, the shape grammar and the space surface equation theory. Various 3D entities such as building grounds, building walls and building domes with fractal characteristics could be generated in a short time by using the computer program. These generative 3D entities were saved in a component database which could help to accumulate design knowledge through continuous expansion. A building could successfully be formed by the designers through selecting proper building grounds, walls and domes from this database. The effectiveness of the proposed method was approved with a case study.
