Genetic Algorithm-Based Scheme Generation for Mechanical Products in Conceptual Design

Currently, the mechanical products assistance design systems mainly focus on the detailed design and the function of mathematics models are often been neglected. In order to solve these problems, a application of mechanical products conceptual design is studied using Enhanced Genetic Algorithm (EGA) in this paper. The conceptual design system is established based on Object-oriented Knowledge representation, and at last a design case of conceptual innovation design is given.

Mechanical products design process always focuses on the description of product structure information, while lacking of the expression and application of function and knowledge information. This paper proposes an intelligent design approach of mechanical products based on Function-Knowledge-Structure (FKS). The gene coding of function, knowledge and structure are constructed, and the correlation matrix of the Functional-Structure (FS) and Knowledge-Structure (KS) are introduced to calculate the fitness function. A case study of the conceptual design on bag forming, filling and sealing machine shows the intelligent design process based on FKS.

Important Significance

On the foundation summing up existing intelligent conceptual design method, this paper puts forward the research content, characters, path, and method of the conceptual design of extension for mechanical products. This paper rounds the core technology of intelligent conceptual design to research the modeling method of extension design in function-principle-layout-configuration. It includes the function expression, function decomposition and synthesis, function illation and decision. The computers are utilized to simulate the human dialectic thought when resolve problems in this method. The given example shows that the extension method has been applied in the field of conceptual design for mechanical products. This method has important significance to resolve the bottleneck problem of theory studying and engineering realizing of intelligent CAD.
