| Abstract: | This paper discusses the differences between the structural theoretic model and actual model used for engineering and the modification methods for the theoretic model, makes research for the fundamental theory of the genetic algorithm and points out the applicability of the theory to the optimal modification of the model. Combining the structural vibration theory with the genetic algorithm, the paper further proposes the considerations and a method for modifying the model by the genetic algorithm and specifically carries out implementation of the method. Finally, the paper also verifies the method by a calculation example. |
