Research on Design Method of Electromechanical Product Form Based on MA-GA

Abstract:

In electromechanical products form design, there still exist problems such as CAD supporting incompletely and low-usage of existent excellent case form information, this paper proposed a comprehensive method of product form design, which integrated morphological matrix, BP network, Analytical Hierarchy Process (AHP), Gray Relating Analyze (GRA) and Genetic Algorithms. According to the heritability of product form features, this method deconstructed case product modeling components and form elements to obtain the form features, then the features and feature values of product form were represented by morphologic matrix, finally product form design scheme were combined with reasonable solutions. Grading method and AHP were used to quantify the modeling components feature, form elements and perceptual image vocabularies of case product, and a BP network model was trained for form scheme image prediction. This article constructed the genetic algorithm fitness function with the weighed grey relation grade to optimize the product form scheme based on customers’ requirements. VC++ was applied to develop the design software, the design of electric bicycle form scheme was taken to illustrate the application process of this method.
