| Abstract: | For the structural topology optimization problem with the obj ective function being the structural compliance and its volume constraint,a new interpolation filtering function and a moving asymptotes approximation are introduced.Based on the guide-weight method and the design space adj ustment technology,a new structural topology optimization method for minimizing the structural compliance is proposed .The results show that the proposed method is of a less number of iterations and a faster convergence speed than the convention-al method. |
