Abstract The IFBMDA is an Information-Flow-Based model for Mechanical Design Automation. This paper first analyzes the mechanical design process from the views of design methodology and cognitive model. Then, two essential assumptions about mechanical design behavior are provided. Based on the analysis and fundamental assumptions, this paper thoroughly describes five submodels which constitute the automation model IFBMDA. They are Information Flow model, Knowledge Processing model, Non-monotonic Expansion Search model, Iterative Constraint Generation and Solution model and Design Process Stage model. Then, this paper also evaluates the model in both practical and theoretical aspects and shows that it is well-developed in both aspects. Finally, the perspective of further mechanical design automation research is outlined.

Abstract As the complexity of mechanical design increases, due to larger size mathematical models, the need for rational design procedures also goes up. As shown elsewhere, dichromatic graphs have proven their value as tools for the algorithmic education of mechanical engineers. This paper analyzes the worth of such graphs as a means to achieve rational design solutions in complex industrial problems. The paper covers plant maintenance and research & development professional case studies. A real-life problem in electromechanical system reengineering is the first application example. Attention is also given in the paper on the partitioning of large problems, involving many variables and relations. The design of a planetary gear unit, with a three-digit number of elements in the mathematical model, is an example problem in this area. In addition, changes and extensions to the computational problem solving theory are included.

This article explains the concept and various aspects of mechanical design automation (MDA). The use of computers for mechanical design is often referred to as MDA. Serious commercialization of computer graphics for design and drafting began in 1969 with the founding of Computervision and Application. The commercial market picked up significantly in 1975, when new 19-inch storage tube display terminals became readily available from Tektronix. These units could be used with minicomputers without custom interfaces, and they could display substantially larger drawings than the older, 11-inch units. The 1980s saw tremendous growth and change in mechanical design automation. While the predominant computer continued to be the 16-bit Digital PDP-11, there was growing interest in Digital’s 32-bit VAX 11 /780. Display products were starting their transition from Tektronix’s storage tube units to raster displays, with color raster just around the corner. The 1990s was a decade of constant movement for the MDA industry.
